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.

The MIO routing registers can be programmed 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 to the PL on the EMIO interfaces. Some of these situations are described in MIO-EMIO Interface Routing Options .
