Depending on the TIOS bit for the corresponding channel, these registers are used to latch the value
of the free-running counter when a defined transition is sensed by the corresponding input capture edge
detector or to trigger an output action for output compare.
Read anytime. Write anytime for output compare function. Writes to these registers have no meaning
or effect during input capture. All timer input capture/output compare registers are reset to $0000.
Read or write anytime.
PAEN — Pulse Accumulator System Enable
0 = Pulse accumulator system disabled
1 = Pulse accumulator system enabled
PAEN is independent from TEN.
PAMOD — Pulse Accumulator Mode
0 = Event counter mode
1 = Gated time accumulation mode
