6.15.4.3
The comparator generates an output ACMPnO (ACMPSR). If the ACMPIE (ACMPCR0[1]) bit in
ACMPCR0 is set, a state change on the comparator output ACMPnO (ACMPSR) will cause
comparator flag ACMPnIF (ACMPSR) be set and the comparator interrupt requested. User can write 1
to ACMPnIF (ACMPSR) through software to stop interrupt request.
