Pulse Accumulator B System Enable — PBEN is independent from TEN. With timer disabled, the pulse
accumulator can still function unless pulse accumulator is disabled.

the PACB 16-bit pulse accumulator B. When PACB is enabled, the PACN1 and PACN0 registers contents are
respectively the high and low byte of the PACB.
PA1EN and PA0EN control bits in ICPAR have no effect.
The PACB shares the input pin with IC0.
