2.9.5 VCC_IO Usage
The VCC_IO voltages for the I/O banks located on the module connector are configurable by applying the
required voltage to the VCC_IO_B[x], respectively VCC_CFG_[x] pins. All VCC_IO_B[x] or VCC_CFG_[x] pins of
the same bank must be connected to the same voltage.
For compatibility with other Enclustra Mercury modules, it is recommended to use a single I/O voltage per
module connector.
