PmodIOXP User Guide
Welcome to the PmodIOXP User Guide! This is a place where you can learn some more of the finer details on how to the work the PmodIOXP without having to dig through its respective datasheet. That being said, all of the information you find here and more can be found in the Analog Devices ADP5589 datasheet. What I will do here is parse out the information I think is helpful to know and provide a little more information on how one might interface with the Pmod.
PmodIOXP Configuration Options
However, as I am finishing up the remaining 12 Pmod reference manuals (as of May 8th, 2015), I will instead say that all of the detailed register descriptions including register addresses, and what the individual bits do are available beginning on page 23 of the ADP5589 datasheet.
