PAIF — Pulse Accumulator Input Edge Flag
TCBYP — Timer Divider Chain Bypass
PCBYP — Pulse Accumulator Divider Chain Bypass
Set when the selected edge is detected at the pulse accumulator
input pin. In event mode, the event edge triggers PAIF. In gated time
accumulation mode, the trailing edge of the gate signal at the pulse
accumulator input pin triggers PAIF. This bit is cleared automatically
by a write to the PAFLG register with bit 0 set.
Full count register access should take place in one clock cycle. A
separate read/write for high byte and low byte will give a different
result than accessing them as a word.
Read or write anytime.
Read anytime. Write only in special mode (SMODN = 0)
