Summary
Possible RTC Alarm Mask Settings.
Description
The RTC peripheral while operating in RTCC mode will generate an alarm by matching the configured alarm time and date with current time and date. The date and time field to be considered while matching are specified with the RTC Alarm Mask. This mask should be specified in the RTC_RTCCAlarmSet() function.
For example, setting the mask to RTC_ALARM_MASK_MMSS will only match the minute and the seconds field of the specified alarm time and will ignore all other fields.
Remarks
None.
