OC1M[5:1] â OC1 Mask Field
OC1M[5:1] correspond to OC[5:1].
0 = Corresponding output compare pin is not affected by OC1 compare.
1 = Corresponding output compare pin is affected by OC1 compare.
OC1D[5:1] â OC1 Data Field
OC1D[5:1] correspond to OC[5:1].
0 = If OC1 mask bit is set, clear the corresponding output compare pin on OC1
match.
1 = If OC1 mask bit is set, the set corresponding output compare pin on OC1
match.
D.8.6 Timer Counter Register
TCNT â Timer Counter Register
$YFF90A
TCNT is the 16-bit free-running counter associated with the input capture, output com-
pare, and pulse accumulator functions of the GPT module.

PACTL enables the pulse accumulator and selects either event counting or gated
mode. In event counting mode, PACNT is incremented each time an event occurs. In
gated mode, it is incremented by an internal clock.
PAIS â PAI Pin State (Read Only)
PAEN â Pulse Accumulator Enable
0 = Pulse accumulator disabled.
1 = Pulse accumulator enabled.
PAMOD â Pulse Accumulator Mode
0 = External event counting.
1 = Gated time accumulation.
PEDGE â Pulse Accumulator Edge Control
The effects of PAMOD and PEDGE are shown in Table D-44.
