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)
