24.7 Events

The RTC can generate the events described in the following table:

PIT_DIV128Prescaled RTC clock divided by 128Given by prescaled RTC clock divided by 128
PIT_DIV64Prescaled RTC clock divided by 64Given by prescaled RTC clock divided by 64

The conditions for generating the OVF and CMP events are identical to those that will raise the corresponding interrupt flags in the RTC.INTFLAGS register.

Refer to the Event System (EVSYS) section for more details regarding event users and Event System configuration.
