3.2 Peripheral Multiplexing on I/O lines
3.2.1 Multiplexed Signals
Each GPIO line can be assigned to one of the peripheral functions. The following table
describes the peripheral signals multiplexed to the GPIO lines.
Note that GPIO 44 is physically implemented in silicon but it must be kept unused and config-
ured in input mode.
