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 2). |
|
2 — PL_INT_NUM_2: |
Interrupt line 2 (mapped to I/O line 4). |
|
3 — PL_INT_NUM_3: |
Interrupt line 3 (mapped to I/O line 6). |
|
4 — PL_INT_NUM_4: |
Interrupt line 4 (mapped to I/O line 1). |
|
5 — PL_INT_NUM_5: |
Interrupt line 5 (mapped to I/O line 3). |
|
6 — PL_INT_NUM_6: |
Interrupt line 6 (mapped to I/O line 5). |
|
7 — PL_INT_NUM_7: |
Interrupt line 7 (mapped to I/O line 7). |
|
8 — PL_INT_NULL: |
This is a NULL interrupt line that does not physically exist. |
