Details

The selected interrupt line can be enabled or disabled using the io.intenabled property. A state change on enabled interrupt lines causes the on_io_int event generation.

In order to work correctly as an interrupt on certain platforms, the line may need to be configured as an input — see Controlling Output Buffers for details.
