Events

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

Table 1. RTC Event Generators
Generator Name Description Event Type Clock Domain Length of the Event
Module Event
RTC OVF Overflow Pulse CLK_RTC One CLK_RTC period
CMP Compare Match One CLK_RTC period
PIT_DIV8192 Prescaled RTC clock divided by 8192 Level Given by prescaled RTC clock divided by 8192
PIT_DIV4096 Prescaled RTC clock divided by 4096 Given by prescaled RTC clock divided by 4096
PIT_DIV2048 Prescaled RTC clock divided by 2048 Given by prescaled RTC clock divided by 2048
PIT_DIV1024 Prescaled RTC clock divided by 1024 Given by prescaled RTC clock divided by 1024
PIT_DIV512 Prescaled RTC clock divided by 512 Given by prescaled RTC clock divided by 512
PIT_DIV256 Prescaled RTC clock divided by 256 Given by prescaled RTC clock divided by 256
PIT_DIV128 Prescaled RTC clock divided by 128 Given by prescaled RTC clock divided by 128
PIT_DIV64 Prescaled RTC clock divided by 64 Given 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 EVSYS - Event System section for more details regarding event users and Event System configuration.
