LPC2109/2119/2129 Single-chip 16/32-bit microcontrollers; 64/128/256 kB ISP/IAP flash with 10-bit ADC and CAN Rev. 7 — 14 June 2011 Product data sheet 1. General description The LPC2109/2119/2129 are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, together with 64/128/256 kB of embedded high-speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at maximum clock rate. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 % with minimal performance penalty. With their compact 64-pin package, low power consumption, various 32-bit timers, 4-channel 10-bit ADC, two advanced CAN channels, PWM channels and 46 fast GPIO lines with up to nine external interrupt pins these microcontrollers are particularly suitable for automotive and industrial control applications, as well as medical systems and fault-tolerant maintenance buses. With a wide range of additional serial communications interfaces, they are also suited for communication gateways and protocol converters as well as many other general-purpose applications. Remark: Throughout the data sheet, the term LPC2109/2119/2129 will apply to devices with and without the /00 or /01 suffixes. The /00 or the /01 suffix will be used to differentiate from other devices only when necessary. 2. Features and benefits 2.1 Key features brought by LPC2109/2119/2129/01 devices  Fast GPIO ports enable port pin toggling up to 3.5 times faster than the original device. They also allow for a port pin to be read at any time regardless of its function.  Dedicated result registers for ADC(s) reduce interrupt overhead. The ADC pads are 5 V tolerant when configured for digital I/O function(s).  UART0/1 include fractional baud rate generator, auto-bauding capabilities and handshake flow-control fully implemented in hardware.  Buffered SSP serial controller supporting SPI, 4-wire SSI, and Microwire formats.  SPI programmable data length and master mode enhancement.  Diversified Code Read Protection (CRP) enables different security levels to be implemented.

Rev. 7 — 14 June 2011 © NXP B.V. 2011. All rights reserved. 9 of 46 NXP Semiconductors LPC2109/2119/2129 Single-chip 16/32-bit microcontrollers 6. Functional description Details of the LPC2109/2119/2129 systems and peripheral functions are described in the following sections. 6.1 Architectural overview The ARM7TDMI-S is a general purpose 32-bit microprocessor, which offers high performance and very low power consumption. The ARM architecture is based on Reduced Instruction Set Computer (RISC) principles, and the instruction set and related decode mechanism are much simpler than those of microprogrammed Complex Instruction Set Computers. This simplicity results in a high instruction throughput and impressive real-time interrupt response from a small and cost-effective processor core. Pipeline techniques are employed so that all parts of the processing and memory systems can operate continuously. Typically, while one instruction is being executed, its successor is being decoded, and a third instruction is being fetched from memory. The ARM7TDMI-S processor also employs a unique architectural strategy known as Thumb, which makes it ideally suited to high-volume applications with memory restrictions, or applications where code density is an issue. The key idea behind Thumb is that of a super-reduced instruction set. Essentially, the ARM7TDMI-S processor has two instruction sets: • The standard 32-bit ARM set. • A 16-bit Thumb set. The Thumb set’s 16-bit instruction length allows it to approach twice the density of standard ARM code while retaining most of the ARM’s performance advantage over a traditional 16-bit processor using 16-bit registers. This is possible because Thumb code operates on the same 32-bit register set as ARM code. Thumb code is able to provide up to 65 % of the code size of ARM, and 160 % of the performance of an equivalent ARM processor connected to a 16-bit memory system. 6.2 On-chip flash program memory The LPC2109/2119/2129 incorporate a 64/128/256 kB flash memory system, respectively. This memory may be used for both code and data storage. Programming of the flash memory may be accomplished in several ways. It may be programmed In System via the serial port. The application program may also erase and/or program the flash while the application is running, allowing a great degree of flexibility for data storage field firmware upgrades, etc. When on-chip bootloader is used, 60/120/248 kB of flash memory is available for user code. The LPC2109/2119/2129 flash memory provides a minimum of 100000 erase/write cycles and 20 years of data retention. On-chip bootloader (as of revision 1.60) provides Code Read Protection (CRP) for the LPC2109/2119/2129 on-chip flash memory. When the CRP is enabled, the JTAG debug port and ISP commands accessing either the on-chip RAM or flash memory are disabled.

All rights reserved. 10 of 46 NXP Semiconductors LPC2109/2119/2129 Single-chip 16/32-bit microcontrollers However, the ISP flash erase command can be executed at any time (no matter whether the CRP is on or off). Removal of CRP is achieved by erasure of full on-chip user flash. With the CRP off, full access to the chip via the JTAG and/or ISP is restored. 6.3 On-chip SRAM On-chip SRAM may be used for code and/or data storage. The SRAM may be accessed as 8 bit, 16 bit, and 32 bit. The LPC2109/2119/2129 provide 8 kB of SRAM for the LPC2109 and 16 kB for the LPC2119 and LPC2129. 6.4 Memory map The LPC2109/2119/2129 memory maps incorporate several distinct regions, as shown in Figure 3. In addition, the CPU interrupt vectors may be re-mapped to allow them to reside in either flash memory (the default) or on-chip SRAM. This is described in Section 6.18 “System control”.

LPC2109/2119/2129 memory map 6.5 Interrupt controller The Vectored Interrupt Controller (VIC) accepts all of the interrupt request inputs and categorizes them as Fast Interrupt reQuest (FIQ), vectored Interrupt reQuest (IRQ), and non-vectored IRQ as defined by programmable settings. The programmable assignment scheme means that priorities of interrupts from the various peripherals can be dynamically assigned and adjusted. FIQ has the highest priority. If more than one request is assigned to FIQ, the VIC combines the requests to produce the FIQ signal to the ARM processor. The fastest possible FIQ latency is achieved when only one request is classified as FIQ because then the FIQ service routine can simply start dealing with that device. But if more than one request is assigned to the FIQ class, the FIQ service routine can read a word from the VIC that identifies which FIQ source(s) is (are) requesting an interrupt.

All rights reserved. 12 of 46 NXP Semiconductors LPC2109/2119/2129 Single-chip 16/32-bit microcontrollers Vectored IRQs have the middle priority. Sixteen of the interrupt requests can be assigned to this category. Any of the interrupt requests can be assigned to any of the 16 vectored IRQ slots, among which slot 0 has the highest priority and slot 15 has the lowest. Non-vectored IRQs have the lowest priority. The VIC combines the requests from all the vectored and non-vectored IRQs to produce the IRQ signal to the ARM processor. The IRQ service routine can start by reading a register from the VIC and jumping there. If any of the vectored IRQs are requesting, the VIC provides the address of the highest-priority requesting IRQs service routine, otherwise it provides the address of a default routine that is shared by all the non-vectored IRQs. The default routine can read another VIC register to see what IRQs are active. 6.5.1 Interrupt sources Table 4 lists the interrupt sources for each peripheral function. Each peripheral device has one interrupt line connected to the Vectored Interrupt Controller, but may have several internal interrupt flags. Individual interrupt flags may also represent more than one interrupt source. Table 4.

Configuration registers control the multiplexers to allow connection between the pin and the on-chip peripherals. Peripherals should be connected to the appropriate pins prior to being activated, and prior to any related interrupt(s) being enabled. Activity of any enabled peripheral function that is not mapped to a related pin should be considered undefined. 6.7 General purpose parallel I/O (GPIO) and Fast I/O Device pins that are not connected to a specific peripheral function are controlled by the parallel I/O registers. Pins may be dynamically configured as inputs or outputs. Separate registers allow setting or clearing any number of outputs simultaneously. The value of the output register may be read back, as well as the current state of the port pins. 6.7.1 Features • Bit-level set and clear registers allow a single instruction set or clear of any number of bits in one port. • Direction control of individual bits. • Separate control of output set and clear. • All I/O default to inputs after reset. 6.7.2 Features added with the Fast GPIO set of registers available on LPC2109/2119/2129/01 only • Fast GPIO registers are relocated to the ARM local bus for the fastest possible I/O timing, enabling port pin toggling up to 3.5 times faster than earlier LPC2000 devices. • Mask registers allow treating sets of port bits as a group, leaving other bits unchanged. • All Fast GPIO registers are byte addressable. • Entire port value can be written in one instruction. • Ports are accessible via either the legacy group of registers (GPIOs) or the group of registers providing accelerated port access (Fast GPIOs).

Each device is recognized by a unique address and can operate as either a receiver-only device (e.g. an LCD driver or a transmitter with the capability to both receive and send information (such as memory). Transmitters and/or receivers can operate in either master or slave mode, depending on whether the chip has to initiate a data transfer or is only addressed. The I2C-bus is a multi-master bus; it can be controlled by more than one bus master connected to it. The I2C-bus implemented in LPC2109/2119/2129 supports a bit rate up to 400 kbit/s (Fast I2C-bus). 6.11.1 Features • Standard I2C-bus compliant interface. • Easy to configure as Master, Slave, or Master/Slave. • Programmable clocks allow versatile rate control. • Bidirectional data transfer between masters and slaves. • Multi-master bus (no central master). • Arbitration between simultaneously transmitting masters without corruption of serial data on the bus. • Serial clock synchronization allows devices with different bit rates to communicate via one serial bus. • Serial clock synchronization can be used as a handshake mechanism to suspend and resume serial transfer. • The I2C-bus may be used for test and diagnostic purposes.

The SPI is a full duplex serial interface, designed to be able to handle multiple masters and slaves connected to a given bus. Only a single master and a single slave can communicate on the interface during a given data transfer. During a data transfer the master always sends a byte of data to the slave, and the slave always sends a byte of data to the master. 6.12.1 Features • Compliant with Serial Peripheral Interface (SPI) specification. • Synchronous, Serial, Full Duplex communication. • Combined SPI master and slave. • Maximum data bit rate of 1⁄8 of the input clock rate. 6.12.2 Features available in LPC2109/2119/2129/01 only • Eight to 16 bits per frame. • When the SPI interface is used in Master mode, the SSELn pin is not needed (can be used for a different function). 6.13 SSP controller (LPC2109/2119/2129/01 only) Remark: This peripheral is available in LPC2109/2119/2129/01 only. The SSP is a controller capable of operation on a SPI, 4-wire SSI, or Microwire bus. It can interact with multiple masters and slaves on the bus. Only a single master and a single slave can communicate on the bus during a given data transfer. Data transfers are in principle full duplex, with frames of four to 16 bits of data flowing from the master to the slave and from the slave to the master. While the SSP and SPI1 peripherals share the same physical pins, it is not possible to have both of these two peripherals active at the same time. Application can switch on the fly from SPI1 to SSP and back. 6.13.1 Features • Compatible with Motorola’s SPI, Texas Instrument’s 4-wire SSI, and National Semiconductor’s Microwire buses. • Synchronous serial communication. • Master or slave operation. • 8-frame FIFOs for both transmit and receive. • Four to 16 bits per frame. 6.14 General purpose timers The Timer/Counter is designed to count cycles of the peripheral clock (PCLK) or an externally supplied clock and optionally generate interrupts or perform other actions at specified timer values, based on four match registers. It also includes four capture inputs LPC2109_2119_2129 Product data sheet All information provided in this document is subject to legal disclaimers. Rev. 7 — 14 June 2011 © NXP B.V. 2011. All rights reserved. 17 of 46 NXP Semiconductors LPC2109/2119/2129 Single-chip 16/32-bit microcontrollers to trap the timer value when an input signal transitions, optionally generating an interrupt. Multiple pins can be selected to perform a single capture or match function, providing an application with ‘or’ and ‘and’, as well as ‘broadcast’ functions among them. 6.14.1 Features • A 32-bit Timer/Counter with a programmable 32-bit Prescaler. • Timer or external event counter operation • Four 32-bit capture channels per timer that can take a snapshot of the timer value when an input signal transitions. A capture event may also optionally generate an interrupt. • Four 32-bit match registers that allow: – Continuous operation with optional interrupt generation on match. – Stop timer on match with optional interrupt generation. – Reset timer on match with optional interrupt generation. • Four external outputs per timer corresponding to match registers, with the following capabilities: – Set LOW on match. – Set HIGH on match. – Toggle on match. – Do nothing on match. 6.14.2 Features available in LPC2109/2119/2129/01 only The LPC2109/2119/2129/01 can count external events on one of the capture inputs if the external pulse lasts at least one half of the period of the PCLK. In this configuration, unused capture lines can be selected as regular timer capture inputs, or used as external interrupts. • Timer can count cycles of either the peripheral clock (PCLK) or an externally supplied clock. • When counting cycles of an externally supplied clock, only one of the timer’s capture inputs can be selected as the timer’s clock. The rate of such a clock is limited to PCLK / 4. Duration of HIGH/LOW levels on the selected CAPn input cannot be shorter than 1 / (2PCLK). 6.15 Watchdog timer The purpose of the watchdog is to reset the microcontroller within a reasonable amount of time if it enters an erroneous state. When enabled, the watchdog will generate a system reset if the user program fails to ‘feed’ (or reload) the watchdog within a predetermined amount of time. 6.15.1 Features • Internally resets chip if not periodically reloaded. • Debug mode.

All rights reserved. 18 of 46 NXP Semiconductors LPC2109/2119/2129 Single-chip 16/32-bit microcontrollers • Enabled by software but requires a hardware reset or a watchdog reset/interrupt to be disabled. • Incorrect/incomplete feed sequence causes reset/interrupt if enabled. • Flag to indicate watchdog reset. • Programmable 32-bit timer with internal pre-scaler. • Selectable time period from (Tcy(PCLK)  256  4) to (Tcy(PCLK)  232  4) in multiples of Tcy(PCLK)  4. 6.16 Real-time clock The RTC is designed to provide a set of counters to measure time when normal or idle operating mode is selected. The RTC has been designed to use little power, making it suitable for battery powered systems where the CPU is not running continuously (Idle mode). 6.16.1 Features • Measures the passage of time to maintain a calendar and clock. • Ultra low power design to support battery powered systems. • Provides Seconds, Minutes, Hours, Day of Month, Month, Year, Day of Week, and Day of Year. • Programmable reference clock divider allows adjustment of the RTC to match various crystal frequencies. 6.17 Pulse width modulator The PWM is based on the standard Timer block and inherits all of its features, although only the PWM function is pinned out on the LPC2109/2119/2129. The Timer is designed to count cycles of the peripheral clock (PCLK) and optionally generate interrupts or perform other actions when specified timer values occur, based on seven match registers. The PWM function is also based on match register events. The ability to separately control rising and falling edge locations allows the PWM to be used for more applications. For instance, multi-phase motor control typically requires three non-overlapping PWM outputs with individual control of all three pulse widths and positions. Two match registers can be used to provide a single edge controlled PWM output. One match register (MR0) controls the PWM cycle rate, by resetting the count upon match. The other match register controls the PWM edge position. Additional single edge controlled PWM outputs require only one match register each, since the repetition rate is the same for all PWM outputs. Multiple single edge controlled PWM outputs will all have a rising edge at the beginning of each PWM cycle, when an MR0 match occurs.

All rights reserved. 19 of 46 NXP Semiconductors LPC2109/2119/2129 Single-chip 16/32-bit microcontrollers Three match registers can be used to provide a PWM output with both edges controlled. Again, the MR0 match register controls the PWM cycle rate. The other match registers control the two PWM edge positions. Additional double edge controlled PWM outputs require only two match registers each, since the repetition rate is the same for all PWM outputs. With double edge controlled PWM outputs, specific match registers control the rising and falling edge of the output. This allows both positive going PWM pulses (when the rising edge occurs prior to the falling edge), and negative going PWM pulses (when the falling edge occurs prior to the rising edge). 6.17.1 Features • Seven match registers allow up to six single edge controlled or three double edge controlled PWM outputs, or a mix of both types. • The match registers also allow: – Continuous operation with optional interrupt generation on match. – Stop timer on match with optional interrupt generation. – Reset timer on match with optional interrupt generation. • Supports single edge controlled and/or double edge controlled PWM outputs. Single edge controlled PWM outputs all go HIGH at the beginning of each cycle unless the output is a constant LOW. Double edge controlled PWM outputs can have either edge occur at any position within a cycle. This allows for both positive going and negative going pulses. • Pulse period and width can be any number of timer counts. This allows complete flexibility in the trade-off between resolution and repetition rate. All PWM outputs will occur at the same repetition rate. • Double edge controlled PWM outputs can be programmed to be either positive going or negative going pulses. • Match register updates are synchronized with pulse outputs to prevent generation of erroneous pulses. Software must ‘release’ new match values before they can become effective. • May be used as a standard timer if the PWM mode is not enabled. • A 32-bit Timer/Counter with a programmable 32-bit Prescaler. 6.18 System control 6.18.1 Crystal oscillator The oscillator supports crystals in the range of 1 MHz to 30 MHz. The oscillator output frequency is called fosc and the ARM processor clock frequency is referred to as CCLK for purposes of rate equations, etc.. fosc and CCLK are the same value unless the PLL is running and connected. Refer to Section 6.18.2 “PLL” for additional information. LPC2109_2119_2129 Product data sheet All information provided in this document is subject to legal disclaimers. Rev. 7 — 14 June 2011 © NXP B.V. 2011. All rights reserved. 20 of 46 NXP Semiconductors LPC2109/2119/2129 Single-chip 16/32-bit microcontrollers 6.18.2 PLL The PLL accepts an input clock frequency in the range of 10 MHz to 25 MHz. The input frequency is multiplied up into the range of 10 MHz to 60 MHz with a Current Controlled Oscillator (CCO). The multiplier can be an integer value from 1 to 32 (in practice, the multiplier value cannot be higher than 6 on this family of microcontrollers due to the upper frequency limit of the CPU). The CCO operates in the range of 156 MHz to 320 MHz, so there is an additional divider in the loop to keep the CCO within its frequency range while the PLL is providing the desired output frequency. The output divider may be set to divide by 2, 4, 8, or 16 to produce the output clock. Since the minimum output divider value is 2, it is insured that the PLL output has a 50 % duty cycle. The PLL is turned off and bypassed following a chip Reset and may be enabled by software. The program must configure and activate the PLL, wait for the PLL to Lock, then connect to the PLL as a clock source. The PLL settling time is 100 s. 6.18.3 Reset and wake-up timer Reset has two sources on the LPC2109/2119/2129: the RESET pin and Watchdog Reset. The RESET pin is a Schmitt trigger input pin with an additional glitch filter. Assertion of chip Reset by any source starts the Wake-up Timer (see Wake-up Timer description below), causing the internal chip reset to remain asserted until the external Reset is de-asserted, the oscillator is running, a fixed number of clocks have passed, and the on-chip flash controller has completed its initialization. When the internal Reset is removed, the processor begins executing at address 0, which is the Reset vector. At that point, all of the processor and peripheral registers have been initialized to predetermined values. The wake-up timer ensures that the oscillator and other analog functions required for chip operation are fully functional before the processor is allowed to execute instructions. This is important at power on, all types of Reset, and whenever any of the aforementioned functions are turned off for any reason. Since the oscillator and other functions are turned off during Power-down mode, any wake-up of the processor from Power-down mode makes use of the Wake-up Timer. The Wake-up Timer monitors the crystal oscillator as the means of checking whether it is safe to begin code execution. When power is applied to the chip, or some event caused the chip to exit Power-down mode, some time is required for the oscillator to produce a signal of sufficient amplitude to drive the clock logic. The amount of time depends on many factors, including the rate of VDD ramp (in the case of power on), the type of crystal and its electrical characteristics (if a quartz crystal is used), as well as any other external circuitry (e.g. capacitors), and the characteristics of the oscillator itself under the existing ambient conditions. 6.18.4 Code security (Code Read Protection - CRP) This feature of the LPC2109/2119/2129 allows the user to enable different levels of security in the system so that access to the on-chip flash and use of the JTAG and ISP can be restricted. When needed, CRP is invoked by programming a specific pattern into a dedicated flash location. IAP commands are not affected by the CRP. There are three levels of the Code Read Protection. LPC2109_2119_2129 Product data sheet All information provided in this document is subject to legal disclaimers. Rev. 7 — 14 June 2011 © NXP B.V. 2011. All rights reserved. 21 of 46 NXP Semiconductors LPC2109/2119/2129 Single-chip 16/32-bit microcontrollers CAUTION CRP1 disables access to chip via the JTAG and allows partial flash update (excluding flash sector 0) using a limited set of the ISP commands. This mode is useful when CRP is required and flash field updates are needed but all sectors can not be erased. CRP2 disables access to chip via the JTAG and only allows full flash erase and update using a reduced set of the ISP commands. Running an application with level CRP3 selected fully disables any access to chip via the JTAG pins and the ISP. This mode effectively disables ISP override using P0[14] pin, too. It is up to the user’s application to provide (if needed) flash update mechanism using IAP calls or call reinvoke ISP command to enable flash update via UART0. If level three Code Read Protection (CRP3) is selected, no future factory testing can be performed on the device. Remark: Devices without the suffix /00 or /01 have only a security level equivalent to CRP2 available. 6.18.5 External interrupt inputs The LPC2109/2119/2129 include up to nine edge or level sensitive External Interrupt Inputs as selectable pin functions. When the pins are combined, external events can be processed as four independent interrupt signals. The External Interrupt Inputs can optionally be used to wake up the processor from Power-down mode. 6.18.6 Memory mapping control The Memory Mapping Control alters the mapping of the interrupt vectors that appear beginning at address 0x0000 0000. Vectors may be mapped to the bottom of the on-chip flash memory, or to the on-chip SRAM. This allows code running in different memory spaces to have control of the interrupts. 6.18.7 Power control The LPC2109/2119/2129 support two reduced power modes: Idle mode and Power-down mode. In Idle mode, execution of instructions is suspended until either a Reset or interrupt occurs. Peripheral functions continue operation during Idle mode and may generate interrupts to cause the processor to resume execution. Idle mode eliminates power used by the processor itself, memory systems and related controllers, and internal buses. In Power-down mode, the oscillator is shut down and the chip receives no internal clocks. The processor state and registers, peripheral registers, and internal SRAM values are preserved throughout Power-down mode and the logic levels of chip output pins remain static. The Power-down mode can be terminated and normal operation resumed by either a Reset or certain specific interrupts that are able to function without clocks. Since all dynamic operation of the chip is suspended, Power-down mode reduces chip power consumption to nearly zero. A Power Control for Peripherals feature allows individual peripherals to be turned off if they are not needed in the application, resulting in additional power savings.

All rights reserved. 22 of 46 NXP Semiconductors LPC2109/2119/2129 Single-chip 16/32-bit microcontrollers 6.18.8 APB The APB divider determines the relationship between the processor clock (CCLK) and the clock used by peripheral devices (PCLK). The APB divider serves two purposes. The first is to provide peripherals with the desired PCLK via APB so that they can operate at the speed chosen for the ARM processor. In order to achieve this, the APB may be slowed down to 1⁄2 to 1⁄4 of the processor clock rate. Because the APB must work properly at power-up (and its timing cannot be altered if it does not work since the APB divider control registers reside on the APB), the default condition at reset is for the APB to run at 1⁄4 of the processor clock rate. The second purpose of the APB divider is to allow power savings when an application does not require any peripherals to run at the full processor rate. Because the APB divider is connected to the PLL output, the PLL remains active (if it was running) during Idle mode. 6.19 Emulation and debugging The LPC2109/2119/2129 support emulation and debugging via a JTAG serial port. A trace port allows tracing program execution. Debugging and trace functions are multiplexed only with GPIOs on Port 1. This means that all communication, timer and interface peripherals residing on Port 0 are available during the development and debugging phase as they are when the application is run in the embedded system itself. 6.19.1 EmbeddedICE Standard ARM EmbeddedICE logic provides on-chip debug support. The debugging of the target system requires a host computer running the debugger software and an EmbeddedICE protocol convertor. EmbeddedICE protocol convertor converts the Remote Debug Protocol commands to the JTAG data needed to access the ARM core. The ARM core has a Debug Communication Channel function built-in. The debug communication channel allows a program running on the target to communicate with the host debugger or another separate host without stopping the program flow or even entering the debug state. The debug communication channel is accessed as a co-processor 14 by the program running on the ARM7TDMI-S core. The debug communication channel allows the JTAG port to be used for sending and receiving data without affecting the normal program flow. The debug communication channel data and control registers are mapped in to addresses in the EmbeddedICE logic. The JTAG clock (TCK) must be slower than 1⁄6 of the CPU clock (CCLK) for the JTAG interface to operate. 6.19.2 Embedded trace macrocell Since the LPC2109/2119/2129 have significant amounts of on-chip memory, it is not possible to determine how the processor core is operating simply by observing the external pins. The ETM provides real-time trace capability for deeply embedded processor cores. It outputs information about processor execution to the trace port. The ETM is connected directly to the ARM core and not to the main AMBA system bus. It compresses the trace information and exports it through a narrow trace port. An external trace port analyzer must capture the trace information under software debugger control. Instruction trace (or PC trace) shows the flow of execution of the processor and provides a list of all the instructions that were executed. Instruction trace is significantly compressed by only broadcasting branch addresses as well as a set of status signals that indicate the LPC2109_2119_2129 Product data sheet All information provided in this document is subject to legal disclaimers.

Trace information generation can be controlled by selecting the trigger resource. Trigger resources include address comparators, counters and sequencers. Since trace information is compressed the software debugger requires a static image of the code being executed. Self-modifying code can not be traced because of this restriction. 6.19.3 RealMonitor RealMonitor is a configurable software module, developed by ARM Inc., which enables real time debug. It is a lightweight debug monitor that runs in the background while users debug their foreground application. It communicates with the host using the DCC (Debug Communications Channel), which is present in the EmbeddedICE logic. The LPC2109/2119/2129 contain a specific configuration of RealMonitor software programmed into the on-chip flash memory.
