When GPT pins are used as an 8-bit port, DDRGP determines whether pins are input or output and
PORTGP holds the 8-bit data.
DDRGP[7:0] — Port GP Data Direction Register
0 = Input only
1 = Output
When PORTGP is used for general-purpose I/O, each bit in DDRGP determines whether the corre-
sponding PORTGP bit is input or output.
All OC outputs can be controlled by the action of OC1. OC1M contains a mask that determines which
pins are affected, and OC1D determines what the outputs are.
OC1M[5:1] — OC1 Mask Field
0 = Corresponding output compare pin is not affected by OC1 compare.
1 = Corresponding output compare pin is affected by OC1 compare.
OC1M[5:1] correspond to OC[5:1].
OC1D[5:1] — OC1 Data Field
0 = If OC1 mask bit is set, clear the corresponding output compare pin on OC1 match.
1 = If OC1 mask bit is set, set the corresponding output compare pin on OC1 match.
OC1D[5:1] correspond to OC[5:1].
TCNT — Timer Counter Register
$YFF90A
TCNT is the 16-bit free-running counter associated with the input capture, output compare, and pulse
accumulator functions of the GPT module.
PACTL enables the pulse accumulator and selects either event counting or gated mode. In event count-
ing mode, PACNT is incremented each time an event occurs. In gated mode, it is incremented by an
internal clock.
PAIS — PAI Pin State (Read-Only)
PAEN — Pulse Accumulator System Enable
0 = Pulse accumulator disabled
1 = Pulse accumulator enabled
