GPIOx_PTOR field descriptions (continued)
Field Description
0 Corresponding bit in PDORn does not change.
1 Corresponding bit in PDORn is set to the inverse of its existing logic state.
36.3.5 Port Data Input Register (GPIOx_PDIR)
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.

GPIOx_PDIR field descriptions
Field Description
PDI Port Data Input
Reads 0 at the unimplemented pins for a particular device. Pins that are not configured for a digital
function read 0. If the Port Control and Interrupt module is disabled, then the corresponding bit in PDIR
does not update.
0 Pin logic level is logic 0, or is not configured for use by digital function.
1 Pin logic level is logic 1.
36.3.6 Port Data Direction Register (GPIOx_PDDR)
The PDDR configures the individual port pins for input or output.
Address: Base a 14h offset
