CAUTION
Toggling several IOs at the same time can significantly increase the current in a pad group. Caution must
be taken to avoid exceeding maximum current thresholds. Please see data sheet.

Field Description
PDO[x] Pad Data Out
This bit stores the data to be driven out on the external GPIO pad controlled by this register.
0 Logic low value is driven on the corresponding GPIO pad when the pad is configured as an
output
1 Logic high value is driven on the corresponding GPIO pad when the pad is configured as an
output
