RTC masked interrupt status register
| ALRAMF | Alarm A masked flag This flag is set by hardware when the alarm A interrupt occurs. |
| ALRBMF | Alarm B masked flag This flag is set by hardware when the alarm B interrupt occurs. |
| WUTMF | Wakeup timer masked flag This flag is set by hardware when the wakeup timer interrupt occurs. This flag must be cleared by software at least 1.5 RTCCLK periods before WUTF is set to 1 again. |
| TSMF | Timestamp masked flag This flag is set by hardware when a timestamp interrupt occurs. If ITSF flag is set, TSF must be cleared together with ITSF. |
| 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. |
| ITSMF | Internal timestamp masked flag This flag is set by hardware when a timestamp on the internal event occurs and timestampinterrupt is raised. |
