10.1 Real-time Event List

  • Timers, PWM, and IO peripherals generate event triggers which are directly routed to event managers such as ADC, for example, to start measurement/conversion without processor intervention.
  • ADC is connected to nine trigger inputs defined as two groups:
    • One group of eight elements for Timer Counter (TC0 to TC4), ADTRIG and PMW0 event0, PWM0 event1
    • One group of one element for low-rate trigger, RTC
  • UART, USART, SPI, TWI, PWM, CLASSD, AES, SHA, ADC, PIO, TIMER (Capture mode) generate event triggers directly connected to DMA controllers (XDMAC) for data transfer without processor intervention.
  • PWM safety events (faults) are in combinational form and directly routed from event generators (ADC, ACC, PMC, TIMER) to the PWM module.
  • PWM receives external triggers to provide PFC, DC/DC functions.
  • PWM output comparators generate events directly connected to TIMER.
  • PMC safety event (clock failure detection) can be programmed to switch the MCK on a reliable main RC internal clock without processor intervention.
