23.7 Events
The RTC can generate the events described in the following table:
| Generator Name | Description | Event Type | Generating Clock Domain | Length of Event | |||
|---|---|---|---|---|---|---|---|
| Peripheral | Event | ||||||
| RTC | OVF | Overflow | Pulse | CLK_RTC | One CLK_RTC period | ||
| CMP | Compare Match | ||||||
| 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.
