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_NUM_2:

Interrupt line 2 (mapped to I/O line 2).

3 — PL_INT_NUM_3:

Interrupt line 3 (mapped to I/O line 3).

4 — PL_INT_NUM_4:

Interrupt line 4 (mapped to I/O line 4).

5 — PL_INT_NUM_5:

Interrupt line 5 (mapped to I/O line 5).

6 — PL_INT_NUM_6:

Interrupt line 6 (mapped to I/O line 6).

7 — PL_INT_NULL:

This is a NULL interrupt line that does not physically exist.
