23.6 Events
The RTC can generate the events described in the following table:
| Generator Name | Description | Event Type | Generating 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.
