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.
