Real Time Event Management
The events generated by peripherals are designed to be directly routed to peripherals managing/using these
events without processor intervention. Peripherals receiving events contain logic by which to select the one
required.

Embedded Characteristics
Timers, PWM, IO peripherals generate event triggers which are directly routed to event managers such as
ADC or DACC, for example, to start measurement/conversion without processor intervention.
UART, USART, SPI, TWI, SSC, PWM, HSMCI, ADC, DACC, PIO also generate event triggers directly
connected to Peripheral DMA Controller (PDC) for data transfer without processor intervention.
Parallel capture logic is directly embedded in PIO and generates trigger event to Peripheral DMA Controller
to capture data without processor intervention.
PWM security events (faults) are in combinational form and directly routed from event generators (ADC,
ACC, PMC, TIMER) to PWM module.
PMC security event (clock failure detection) can be programmed to switch the MCK on reliable main RC
internal clock without processor intervention.
