东芝

东芝(Toshiba),是日本最大的半导体制造商,也是第二大综合电机制造商,隶属于三井集团。公司创立于1875年7月,原名东京芝浦电气株式会社,1939年由东京电气株式会社和芝浦制作所合并而成,业务领域包括数码产品、电子元器件、社会基础设备、家电等。20世纪80年代以来,东芝从一个以家用电器、重型电机为主体的企业,转变为包括通讯、电子在内的综合电子电器企业。进入90年代,东芝在数字技术、移动通信技术和网络技术等领域取得了飞速发展,成功从家电行业的巨人转变为IT行业的先锋。

MCU

微控制单元(Microcontroller Unit;MCU) ,又称单片微型计算机(Single Chip Microcomputer )或者单片机,是把中央处理器(Central Process Unit;CPU)的频率与规格做适当缩减,并将内存(memory)、计数器(Timer)、USB、A/D转换、UART、PLC、DMA等周边接口,甚至LCD驱动电路都整合在单一芯片上,形成芯片级的计算机,为不同的应用场合做不同组合控制。

32 Bit RISC Microcontroller TX00 Series TMPM061FWFG TMPM061FWFG TMPM061FWFG Introduction: Notes on the description of SFR (Special Function Register) under this specifica- tion An SFR (Special Function Register) is a control register for periperal circuits (IP). The SFR addressses of IPs are described in the chapter on memory map, and the details of SFR are given in the chapter of each IP. Definition of SFR used in this specification is in accordance with the following rules. a. SFR table of each IP as an example ・ SFR tables in each chapter of IP provides register names, addresses and brief descriptions. ・ All registers have a 32-bit unique address and the addresses of the registers are defined as follows, with some exceptions: "Base address + (Unique) address" Control register Register name Base Address = 0x0000_0000 SAMCR Address(Base+) 0x0004 0x000C Note: SAMCR register address is 32 bits wide from the address 0x0000_0004 (Base Address(0x00000000) + unique address (0x0004)). Note: The register shown above is an example for explanation purpose and not for demonstration purpose. This register does not exist in this microcontroller. b. SFR(register) ・ Each register basically consists of a 32-bit register (some exceptions). ・ The description of each register provides bits, bit symbols, types, initial values after reset and func- tions. 1.2.2 SAMCR(Control register) bit symbol After reset bit symbol After reset bit symbol After reset bit symbol After reset 31 - 0 23 - 0 15 - 0 7 MODE 0 30 - 0 22 - 0 14 - 0 6 0 29 - 0 21 - 0 13 - 0 5 0 TMPM061FWFG 25 - 0 17 - 0 9 0 1 0 MODE 24 - 0 16 - 0 8 0 0 0 28 - 0 20 - 0 12 - 0 4 1 26 - 0 18 - 0 10 - 0 2 0 27 - 0 19 - 0 11 - 0 3 TDATA 0 Function Bit 31-10 9-7 Bit Symbol Type − MODE[2:0] R R/W 6-0 TDATA[6:0] W "0" can be read. Operation mode settings 000 : Sample mode 0 001 : Sample mode 1 010 : Sample mode 2 011 : Sample mode 3 The settings other than those above: Reserved Transmitted data Note: The Type is divided into three as shown below. R / W R W READ WRITE READ WRITE c. Data descriptopn Meanings of symbols used in the SFR description are as shown below. ・ x:channel numbers/ports ・ n,m:bit numbers d. Register descriptoption Registers are described as shown below. ・ Register name Exmaple: SAMCR="000" or SAMCR="000" indicates bit 2 to bit 0 in bit symbol mode (3bit width). ・ Register name [Bit] Example: SAMCR[9:7]="000" It indicates bit 9 to bit 7 of the register SAMCR (32 bit width).
