PAOVF — Pulse Accumulator Overflow Flag
PAIF — Pulse Accumulator Input Flag
When the fast flag clear all enable bit, TFFCA, is set, any access to the
pulse accumulator counter registers clears all the flags in TIMPAFLG.

PAOVF is set when the 16-bit pulse accumulator rolls over from
$FFFF to $0000. If the PAOVI bit in TIMPACTL is also set, PAOVF
generates an interrupt request. Clear PAOVF by writing a 1 to it.
PAIF is set when the selected edge is detected at the PAI pin. In event
counter mode, the event edge sets PAIF. In gated time accumulation
mode, the trailing edge of the gate signal at the PAI pin sets PAIF. If
the PAI bit in TIMPACTL is also set, PAIF generates an interrupt
request. Clear PAIF by writing a 1 to it.
