IPL[2:0] — Interrupt Priority Level
This field specifies the priority level of interrupts generated by the GPT.
IVBA[3:0] — Interrupt Vector Base Address
Most significant nibble of interrupt vector numbers generated by the GPT. Refer to Table 61.
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
All OC outputs can be controlled by the action of OC1. OC1M contains a mask that determines which
pins are affected. OC1D determines what the outputs are.
OC1M[5:1] — 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.
