The following application note concerns microcontrollers of the C500 family with a CCUPeripheral Unit on Chip which is similar tSAx-C504-LMSAx-C504-2RMIn block commutation mode, a synchronous generated defined incoming digital signal patternof e.g. hall sensors, which are applied to the INT0-2 inputs, is sampled. Each transition at theINT0-2 inputs results in a change of the state of the PWM outputs according to aimplemented block commutation table in the CCU unit without using CPU load for thisoperation.
