RTC secure masked interrupt status register
| ALRAMF | Alarm A interrupt secure masked flag This flag is set by hardware when the alarm A secure interrupt occurs. |
| ALRBMF | Alarm B interrupt secure masked flag This flag is set by hardware when the alarm B secure interrupt occurs. |
| WUTMF | Wakeup timer interrupt secure masked flag This flag is set by hardware when the wakeup timer secure interrupt occurs. This flag must be cleared by software at least 1.5 RTCCLK periods before WUTF is set to 1 again. |
| TSMF | Timestamp interrupt secure masked flag This flag is set by hardware when a timestamp secure interrupt occurs. |
| TSOVMF | Timestamp overflow interrupt secure masked flag This flag is set by hardware when a timestamp secure 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. |
| SSRUMF | SSR underflow secure masked flag This flag is set by hardware when the SSR underflow secure interrupt occurs. |
