PAEN - PAC Enable Bit
PAMOD - Pulse Accumulator Mode Bit
PAIE - PAC Interrupt Enable Bit
This PAIE bit enables interrupt caused by the PAOF bit.
7.1.2
When PAC is disabled (PAEN=0), the counter will be cleared to zero. This ensures the Counter
starts from zero every time it is disabled and enabled.
The Pulse Accumulator Counter is read only and resets to zero a write operation.
