Note: 1. Refer to ”Electrical Characteristics” on page 50 for a description of the electrical properties of the pin types used.

See Section 3.3 for a description of the various peripheral signals.

3.2.2 Peripheral Functions

Each GPIO line can be assigned to one of several peripheral functions. The following table

describes how the various peripheral functions are selected. The last listed function has priority

in case multiple functions are enabled on the same pin.
