Descriptions
RTC Compare Match Value
A match condition happens when the value in the RTCCNT register is equal to
RTCCMP value. An interrupt can be generated if the CMIEN bit in the RTCIWEN
register is set. When the CMPCLR bit in the RTCCR register is set to 0 and a match
condition happens, the CMFLAG bit in the RTCSR register is set while the value in
the RTCCNT register is not affected and will continue to count until overflow. When
the CMPCLR bit is set to 1 and a match condition happens, the CMFLAG bit in the
RTCSR register is set and the RTCCNT register will be reset to zero and then the
counter continues to count.
