21.5.6 Events
The RTC can generate the following events:
| Generator Name | Description | Event Type | Generating Clock Domain | Length of Event | |
|---|---|---|---|---|---|
| Peripheral | Event | ||||
| RTC | OVF | Overflow | Pulse | CLK_RTC_APB | One CLK_RTC_APB period |
| CMP_n | 32-bit and 16-bit Counter (Mode 0 and 1): Compare n. Clock/Calendar (Mode 2): Alarm n. | Pulse | CLK_RTC_APB | One CLK_RTC_APB period | |
| PER_n | Period Interval n | Pulse | CLK_RTC_APB | One CLK_RTC_APB period | |
Writing a ‘1’ to an Event Output Enable bit in the Event Control register (EVCTRL.xxEO) enables the corresponding output event. Writing a ‘0’ to this bit disables the corresponding output event.
The RTC has no event users or actions.
Refer to the EVSYS - Event System chapter for details on configuring the event system.
