This flag is set by hardware when the SSR underflow interrupt occurs.
This flag is set by hardware when a timestamp on the internal event occurs and
timestampinterrupt is raised.
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.
This flag is set by hardware when a timestamp interrupt occurs.
If ITSF flag is set, TSF must be cleared together with ITSF.
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.
This flag is set by hardware when the alarm A interrupt occurs.
