The multiplexed I/O (MIO) signals include connections from peripherals in the PMC and PS to the MIO pins and the extended MIO (EMIO) signals to the PL fabric.

Program the MIO routing registers for each peripheral controller I/O interface that is required. There are three MIO banks (total of 78 signals) that connect I/O peripherals in the PMC and LPD to the device pins.

If an I/O interface is not routed via an MIO pin, then its interface signal is available on the PL fabric on the EMIO interface. Some of these situations are described in MIO-EMIO Interface Routing Options .
