24.7 Events

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

Table 24-1. RTC Event Generators
Generator Name		Description	Event Type	Clock Domain	Length of the Event
Module	Event	Description	Event Type	Clock Domain	Length of the Event
RTC	OVF	Overflow	Pulse	CLK_RTC	One CLK_RTC period
	CMP	Compare Match	Pulse		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.
