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.
