Real Time Counter (RTC) Peripheral API.
This module contains functions to control the RTC peripheral of Silicon Labs 32-bit MCUs and SoCs. The RTC ensures timekeeping in low energy modes.

RTC_CompareGet()
|
uint32_t RTC_CompareGet
|
(
|
unsigned int
|
comp
|
)
|
|
Get the RTC compare register value.
-
Parameters
-
|
[in]
|
comp
|
A compare register to get. This value must be less than
NUM_RTC_CHANNELS
.
|
-
Returns
-
A compare register value, 0 if invalid register selected.
◆
RTC_CompareSet()
|
void RTC_CompareSet
|
(
|
unsigned int
|
comp,
|
|
|
|
uint32_t
|
value
|
|
|
)
|
|
|
Set the RTC compare register value.

Note
-
The setting of a compare register requires synchronization into the low-frequency domain. If the same register is modified before a previous update has completed, this function will stall until the previous synchronization has completed. This only applies to the Gecko Family. See comments in the regSync() internal function call.
