Configurable GPIO Voltage

Except for GPP_​J, GPP_​S, and GPD groups, all other GPIO groups support per-group configurable voltage, which allows control selection of 1.8 V or 3.3 V for each GPIO group. The voltage of each GPIO group is selected by both connecting the corresponding GPIO power supply pin and setting the corresponding Group Master Voltage Select soft strap to the desired voltage (i.e 3.3 V or 1.8 V).

Notes:
  1. GPP_​J and GPP_​S groups support 1.8 V only.
  2. GPD group supports 3.3 V only.
