40.2.1 Port Data Output Register (GPIOx_PDOR)
This register configures the logic levels that are driven on each general-purpose output
pins.
NOTE
Do not modify pin configuration registers associated with pins
not available in your selected package. All unbonded pins not
available in your package will default to DISABLE state for
lowest power consumption.

Field Description
PDO Port Data Output
Register bits for unbonded pins return a undefined value when read.
0 Logic level 0 is driven on pin, provided pin is configured for general-purpose output.
1 Logic level 1 is driven on pin, provided pin is configured for general-purpose output.
40.2.2 Port Set Output Register (GPIOx_PSOR)
This register configures whether to set the fields of the PDOR.

Field Description
PTSO Port Set Output
Writing to this register will update the contents of the corresponding bit in the PDOR as follows:
0 Corresponding bit in PDORn does not change.
1 Corresponding bit in PDORn is set to logic 1.
