Each of these I/O pins can be routed through MIOs, EMIOs, or GT Lanes as applicable. Each peripheral pin can be routed through a subset of 78 MIOs as required. Alternatively the same pins from each peripheral can be routed to EMIO signals which brings the signal to PL section of the device for further processing.

For more information on the MIO and EMIO, refer to the Multiplexed I/O, chapter 26 in the Zynq UltraScale All Programmable MPSoC Technical Reference Manual (UG1085) [Ref 1] .

MIOs available for peripheral pinouts are divided into three Banks: Bank0 (MIO 0-25), Bank1 (MIO 26-51), and Bank2 (MIO 52-77). Each bank has a common I/O Voltage Standard for all its MIOs and the default value for this is LVCMOS33.
