You can define the label of any pin that can be displayed in user interface for
ease of identification.
Boards and kits have pre-defined labels. However, it is also possible to define
a pin label listed in the Pins and Routing Details views.
The pin identifier is used to generate the #define in the
pin_mux.h file. However, it is an optional parameter. If the parameter is not defined, the
code for #define is not generated. Additionally, you can define multiple
identifiers, using the “;” character as a separator. You can also set the identifier by typing
it directly into the cell in the Identifier column in the Routing Details
views.

A check is implemented to ensure whether the generated defines are duplicated in the
pin_mux.h file. These duplications are indicated in the identifier column
as errors. See Identifier
errors.

You can also select the pin to use in a given routing from the Routing
Details view. However, the identifier must be a valid C identifier and must be used in
the source code.
Figure 4. Pins macros prefix
If multiple functions are used, each individual function can include a special prefix.
Check the Pins > Functional Group Properties > Set custom #define prefix checkbox
to enter prefix of macros in particular function used in the generated code of the pin_mux.h
file. Entered prefix text must be a C identifier. If unchecked, the Function name is
used as a default prefix.
