MINF — Minute Flag
SECF — Second Flag
TB1F — Timebase 1 Flag
TB2F — Timebase 2 Flag
This clearable, read-only bit is set on every increment of the minute
counter. When the MINIE bit in RTCCR1 is set, MINF generates a
CPU interrupt request. In normal operation, clear the MINF bit by
reading RTCSR with MINF set and then reading the minute register
(MINR). Reset clears MINF.
This clearable, read-only bit is set on every increment of the second
counter. When the SECIE bit in RTCCR1 is set, SECF generates a
CPU interrupt request. In normal operation, clear the SECF bit by
reading RTCSR with SECF set and then reading the second register
(SECR). Reset clears SECF.
This clearable, read-only bit is set on every tick of the timebase 1
counter (every 0.5 seconds). When the TB1IE bit in RTCCR1 is set,
TB1F generates a CPU interrupt request. In normal operation, clear
the TB1F bit by reading RTCSR with TB1F set and then reading the
chronograph register (CHRR). Reset clears TB1F.
This clearable, read-only bit is set on every tick of the timebase 2
counter (every 0.25 seconds). When the TB2IE bit in RTCCR1 is set,
TB2F generates a CPU interrupt request. In normal operation, clear
the TB2F bit by reading RTCSR with TB2F set and then reading the
chronograph register (CHRR). Reset clears TB2F.
