RTC status register

Structs§

ALRAF: Alarm %s flag
ITSF: Internal timestamp flag This flag is set by hardware when a timestamp on the internal event occurs.
TSF: Timestamp flag This flag is set by hardware when a timestamp event occurs. If ITSF flag is set, TSF must be cleared together with ITSF.
TSOVF: Timestamp overflow flag This flag is set by hardware when a timestamp event occurs while TSF 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.
WUTF: Wakeup timer flag This flag is set by hardware when the wakeup auto-reload counter reaches 0. This flag must be cleared by software at least 1.5 RTCCLK periods before WUTF is set to 1 again.

ALRF_R: Field ALRF(A,B) reader - Alarm %s flag
ITSF_R: Field ITSF reader - Internal timestamp flag This flag is set by hardware when a timestamp on the internal event occurs.
R: Register SR reader
TSF_R: Field TSF reader - Timestamp flag This flag is set by hardware when a timestamp event occurs. If ITSF flag is set, TSF must be cleared together with ITSF.
TSOVF_R: Field TSOVF reader - Timestamp overflow flag This flag is set by hardware when a timestamp event occurs while TSF 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.
WUTF_R: Field WUTF reader - Wakeup timer flag This flag is set by hardware when the wakeup auto-reload counter reaches 0. This flag must be cleared by software at least 1.5 RTCCLK periods before WUTF is set to 1 again.
