Open-Drain Interrupt Output

The interrupt pin can be configured to trigger

on an event, GPI level, FIFO overflow, logic

function output, and on keyboard lock. The

corresponding bit in the interrupt enable

register must be set in order for the interrupt to

be set. Specific registers related to the

interrupts are described in the ADP5589

datasheet.

Reset Pin

The PmodIOXP has an active-low reset pin

that can be used to reset the ADP5589 to

default settings.

General Purpose I/O (GPIO)

The PmodIOXP has 19 GPIOs that can be

configured a number of ways. The GPIOs can

be set as either input or output, set to decode a

keypad matrix, or implement logic functions.

The functionality of the IOs can be set using

the configuration registers which are described

in the ADP5589 datasheet.
