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.
