13.2.1 GPIO Configuration Table
Some GPIO lines are shared with other interfaces, such as ASC1, SPI (Serial Peripheral Interface) and a status
LED. The following table shows the configuration variants. All variants are mutually exclusive, i.e. a line config-
ured for GPIO usage is locked for alternative use and vice versa.
