Omega Engineering OME-PIO-D96 manual INTCHAN0/1/2/3

2.5.2 INT_CHAN_0/1/2/3
INT_CHAN_0 (1/2/3)	P2C0(P5C0/P8C0/P11C0)
	Inverted/Noninverted select
	INV0(1/2/3)
	Enable/Disable select
	EN0(1/2/3)

The INT_CHAN_0(1/2/3) must be fixed in low level state normally and generated 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 P2C0 (P5C0/P8C0/P11C0)

INV0 (1/2/3) = 1 → INT_CHAN_0(1/2/3) = non-inverted state of P2C0 (P5C0/P8C0/P11C0)
