2.4.2 INT_CHAN_0/1/2/3 |
|
INT_CHAN_0 (1/2/3) | PC0(PC1/PC2/PC3) |
| Inverted/Noninverted select |
| INV0(1/2/3) |
| Enable/Disable select |
| EN0(1/2/3) |
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
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) =
