The INT_CHAN_0 must normally be fixed in low level state and generate a high pulse to interrupt the PC.

The EN0 (EN1/EN2/EN3) can be used to enable/disable the INT_CHAN_0(1/2/3) as follows : (Refer to Sec. 3.3.4)

EN0 (1/2/3) = 0 → INT_CHAN_0(1/2/3) = disable EN0 (1/2/3) = 1 → INT_CHAN_0(1/2/3) = enable

The INV0 can be used to invert/non-invert the PC0 (1/2/3) as follows: (Refer to Sec.3.3.6)

INV0 (1/2/3) = 0 → INT_CHAN_0(1/2/3) = inverted state of PC0 (1/2/3) INV0 (1/2/3) = 1 → INT_CHAN_0(1/2/3) = non-inverted state of PC0 (1/2/3)
