Note:
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.
Table 3-2.
The oscillators are not mapped to the normal GPIO functions and their muxings are controlled
by registers in the Power Mananger (PM). Please refer to the PM chapter for more information
about this.
