Enum pl_int_num contains the list of constants that refer to interrupt I/O lines available on the EM500. Interrupt lines are mapped onto general-purpose I/O lines. Interrupt line 0 corresponds to I/O line 16, interrupt line 1- to I/O line 17, and so on. Keep in mind that for an interrupt line to work you need to configure a corresponding I/O line as input. Do this through the io.num property of the io object.
Enum pl_int_num includes the following constants:
| PL_INT_NUM_0: | Interrupt line 0 (mapped onto I/O line 16). |
| PL_INT_NUM_1: | Interrupt line 1 (mapped onto I/O line 17). |
| PL_INT_NUM_2: | Interrupt line 2 (mapped onto I/O line 18). |
| PL_INT_NUM_3: | Interrupt line 3 (mapped onto I/O line 19). |
| PL_INT_NUM_4: | Interrupt line 4 (mapped onto I/O line 20). |
| PL_INT_NUM_5: | Interrupt line 5 (mapped onto I/O line 21). |
| PL_INT_NUM_6: | Interrupt line 6 (mapped onto I/O line 22). |
| PL_INT_NUM_7: | Interrupt line 7 (mapped onto I/O line 23). |
| PL_INT_NULL: | This is a NULL interrupt line that does not physically exist. |
