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
D.8.4 Port GP Data Direction Register/Data Register
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.
DDGP[7:0] — Port GP Data Direction Register
0 = Input only
1 = Output
D.8.5 OC1 Action Mask Register/Data Register
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.
