RTC masked interrupt status register
| ALRAMF | Alarm A masked flag This flag is set by hardware when the alarm A interrupt occurs. |
| TSMF | Timestamp masked flag This flag is set by hardware when a timestamp interrupt occurs. |
| TSOVMF | Timestamp overflow masked flag This flag is set by hardware when a timestamp interrupt occurs while TSMF is already set. It is recommended to check and then clear TSOVF only after clearing the TSF bit. Otherwise, an overflow might not be noticed if a timestamp event occurs immediately before the TSF bit is cleared. |
