The INTi interrupt is generated by an INTi input. To use the INTi interrupt, set the INTiEN bit in the INTEN
register is to 1 (enabled). The edge polarity is selected using the INTiPL bit in the INTEN register and the POL
bit in the INTiIC register. The input pins used as the INT1 input can be selected.
Also, inputs can be passed through a digital filter with three different sampling clocks.
The INT0 pin is shared with the pulse output forced cutoff input of timer RC, and the external trigger input of
timer RB.
Table 11.6 lists the Pin Configuration of INT Interrupt.
The INTSR register selects which pin is assigned to the INT1 input. To use INT1, set this register.
Set the INTSR register before setting the INT1 associated registers. Also, do not change the setting values in
this register during INT1 operation.
