12. Event System
The events generated by peripherals (source) are designed to be directly routed to peripherals (destination) using
these events without processor intervention. The trigger source can be programmed in the destination peripheral.
12.1 Embedded Characteristics
• Timers, PWM, I/Os and peripherals generate event triggers which are directly routed to destination peripherals,
such as AFEC or DACC to start measurement/conversion without processor intervention.
•
UART, USART, QSPI, SPI, TWI, PWM, HSMCI, AES, AFEC, DACC, PIO, TC (Capture mode) also generate
event triggers directly connected to the DMA Controller for data transfer without processor intervention.
• Parallel capture logic is directly embedded in the PIO and generates trigger events to the DMA Controller to
capture data without processor intervention.
• PWM safety events (faults) are in combinational form and directly routed from event generators (AFEC, ACC,
PMC, TC) to the PWM module.
• PWM output comparators (OCx) generate events directly connected to the TC.
• PMC safety event (clock failure detection) can be programmed to switch the MCK on reliable main RC internal
clock without processor intervention.
