Field Descriptions

RTCCMPV RTC Compare Match Value

A match condition happens when the value in the RTCCNT register is equal to the

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.
