The INTi interrupt is generated by an INTi input. When using the INTi interrupt, the INTiEN bit in the INTEN
register is set to 1 (enable). The edge polarity is selected using the INTiPL bit in the INTEN register and the
POL bit in the INTiIC register. The INT1 input and the INT2 input can select the input pin.
Inputs can be passed through a digital filter with three different sampling clocks.
The INT0 pin is shared with the pulse output forced cutoff of timer RC and timer RD, and the external trigger
input of timer RB.
Figure 12.12 shows the PMR Register, Figure 12.13 shows the INTEN Register, Figure 12.14 shows the INTF
Register, and Figure 12.15 shows the TRAIOC Register
