All bits reset to zero.
The 8-bit pulse accumulators PAC3 and PAC2 can be enabled only if PAEN in PACTL is cleared. If PAEN
is set, PA3EN and PA2EN have no effect.
The 8-bit pulse accumulators PAC1 and PAC0 can be enabled only if PBEN in PBCTL is cleared. If PBEN
is set, PA1EN and PA0EN have no effect.
