Zynq-7000 SoC - What do I do with an unused MIO_VREF pin?


The MIO interface being used by the Zynq design does not require VREF. 

Can I use this as a general I/O like in SelectIO?  How should I connect it?


The VREF pin is dedicated and cannot be used as general I/O.  If unneeded, it should be left floating.

This has been added to the latest version of User Guide 933, Zynq-7000 PCB Design and Pin Planning Guide.
