5.17.4 Functional Description
5.17.4.1 Interrupt Sources
The output of comparators are sampled by PCLK and reflected at CO1 and CO2 of CMPSR
register. If CMP0IE/CMP1IE of CMP0CR/CMP1CR is set to 1, the comparator interrupt will be
enabled. As the output state of comparator is changed, the comparator interrupt will be asserted
and the corresponding flag, CMPF0 or CMPF1, will be set. Software can clear the flag to 0 by
writing 1 to it.
