Zynq-7000 Power - Should MIO Bank 1 voltage selection be pulled High to Vcco_MIO0 or Vcco_MIO1?

Description

In Table 5-3 of the Zynq-7000 PCB Design and Pin Planning Guide (UG933), it states that MIO[8] should be pulled to Vcco_MIO1 to select the voltage for MIO Bank 1.

Is this correct?

Solution

No, this is not correct.

All mode pins are located in MIO bank 0 and need to be pulled to Vcco_MIO0 (when appropriate). Mode pins should never be pulled High to Vcco_MIO1.

Pulling them High to Vcco_MIO1 is potentially damaging to the Zynq device.
