INT Interrupt
INTi Interrupt (i = 0 to 7)
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 pin used as the INTi 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 timer RD, and the external
trigger input of timer RB.
