Enum pl_int_num
Enum pl_int_num contains the list of constants that refer to available interrupt lines. Interrupt lines are mapped to general-purpose I/O (GPIO) lines (this mapping can't be altered). 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 to I/O line 0). |
|
1 — PL_INT_NUM_1: |
Interrupt line 1 (mapped to I/O line 1). |
|
2 — PL_INT_NULL: |
This is a NULL interrupt line that does not physically exist. |
