PAEN — Pulse Accumulator System Enable
PAMOD — Pulse Accumulator Mode
PEDGE — Pulse Accumulator Edge Control
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 is independent from TEN.
For PAMOD = 0 (event counter mode)
For PAMOD = 1 (gated time accumulation mode)
