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. Details on connectivity in I/O banks having generic
names (for example O or N) are presented in Section 2.9.4.

Not all I/Os are available on the module connector. Please check the assembly variants description in Section 2.9.2.
