When the fast flag clear all enable bit, GPTSCR1[TFFCA], is set, any access
to the pulse accumulator counter registers clears all the flags in GPTPAFLG.

Pulse accumulator overflow interrupt enable. Enables the PAOVF flag to generate
interrupt requests.
1 PAOVF interrupt requests enabled
0 PAOVF interrupt requests disabled
Pulse accumulator input interrupt enable. Enables the PAIF flag to generate interrupt
requests.
1 PAIF interrupt requests enabled
0 PAIF interrupt requests disabled
Reserved, should be cleared.
Pulse accumulator overflow flag. Set when the 16-bit pulse accumulator rolls over from
0xFFFF to 0x0000. If the GPTPACTL[PAOVI] bit is also set, PAOVF generates an
interrupt request. Clear PAOVF by writing a 1 to it. This bit is read anytime, write
anytime. (Writing 1 clears the flag; writing 0 has no effect.)
1 Pulse accumulator overflow
0 No pulse accumulator overflow
Pulse accumulator input flag. 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 GPTPACTL
is also set, PAIF generates an interrupt request. Clear PAIF by writing a 1 to it.
1 Active PAI input
0 No active PAI input
