Enum pl_int_num contains the list of constants that refer to available interrupt lines. Interrupt lines are mapped to GPIO lines (this mapping can't be altered). For example, interrupt line 0 corresponds to GPIO line 16, interrupt line 1- to GPIO line 17, and so on. Keep in mind that for an interrupt line to work you need to configure the corresponding GPIO line as input.
Enum pl_int_num includes the following constants:
| 0- PL_INT_NUM_0: | Interrupt line 0 (mapped onto I/O line 16). |
| 1- PL_INT_NUM_1: | Interrupt line 1 (mapped onto I/O line 17). |
| 2- PL_INT_NUM_2: | Interrupt line 2 (mapped onto I/O line 18). |
| 3- PL_INT_NUM_3: | Interrupt line 3 (mapped onto I/O line 19). |
| 4- PL_INT_NUM_4: | Interrupt line 4 (mapped onto I/O line 20). |
| 5- PL_INT_NUM_5: | Interrupt line 5 (mapped onto I/O line 21). |
| 6- PL_INT_NUM_6: | Interrupt line 6 (mapped onto I/O line 22). |
| 7- PL_INT_NUM_7: | Interrupt line 7 (mapped onto I/O line 23). |
| 8- PL_INT_NULL: | This is a NULL interrupt line that does not physically exist. |
