Note that the CFGBVS_0 pin is set automatically to GND (if VCC_CFG_MIO_B12 is less than or equal to 1.8 V)
or to VCCO (if VCC_CFG_MIO_B12 is 2.5 V or 3.3 V).
Warning!
Use only VCC_IO voltages compliant with the equipped SoC device; any other voltages may damage
the equipped SoC device, as well as other devices on the Mercury ZX1 SoC module.
Do not leave a VCC_IO pin floating, as this may damage the equipped SoC device, as well as other
devices on the Mercury ZX1 SoC module.
Warning!
Do not power the VCC_IO pins when PWR_GOOD and PWR_EN signals are not active. If the module
is not powered, you need to make sure that the VCC_IO voltages are disabled (for example, by using a
switch on the base board, which uses PWR_GOOD as enable signal). Figure 10 illustrates the VCC_IO
power requirements.

NAND flash is disabled when VCC_CFG_MIO_B12 is 1.8 V.

The RGMII Ethernet interface is specified only up to 2.5 V on the MIO pins by Xilinx. Please refer to Section 2.20 for details.
4
The LEDs may start to glow when VCC_IO_B34 is less than 1.8 V.
