OC1M[5:1] correspond to OC[5:1].
OC1D[5:1] correspond to OC[5:1].
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.
The effects of PAMOD and PEDGE are shown in
PAEN
0 = Corresponding output compare pin is not affected by OC1 compare.
1 = Corresponding output compare pin is affected by OC1 compare.
0 = If OC1 mask bit is set, clear the corresponding output compare pin on OC1
1 = If OC1 mask bit is set, the set corresponding output compare pin on OC1
0 = Pulse accumulator disabled.
1 = Pulse accumulator enabled.
0 = External event counting.
1 = Gated time accumulation.
