Configuration Items

This section summarizes the symbols used in macro definitions for the static GPIO port
configuration by the driver initialization routine. Symbol x in the table should be replaced with the
name of the GPIO port e.g. GPIO_A_PUR. These symbols are intended for the application
(project) specific configuration file appconfig.h. See e.g. Example 5-246 for more details.
