If for any reason the timer is not active, there is no ÷64 clock for the
pulse accumulator since the E÷64 is generated by the timer prescaler.
TSWAI also affects pulse accumulators and modulus down counters.
TBSCK does not stop the pulse accumulator.

output compare channel ($90–$9F) causes the corresponding
channel flag, CnF, to be cleared. For TFLG2 ($8F), any access
to the TCNT register ($84, $85) clears the TOF flag. Any
access to the PACN3 and PACN2 registers ($A2, $A3) clears
the PAOVF and PAIF flags in the PAFLG register ($A1). Any
access to the PACN1 and PACN0 registers ($A4, $A5) clears
the PBOVF flag in the PBFLG register ($B1). Any access to the
