6. I/O Multiplexing and Considerations
6.1 Multiplexed Signals
By default each pin is controlled by the PORT as a general purpose I/O, and alternatively it can be
assigned a different peripheral functions. To enable a peripheral function on a pin, the Peripheral
Multiplexer Enable bit in the Pin Configuration register corresponding to that pin (PINCFGn.PMUXEN, n =
0-31) in the PORT must be written to '1'. The selection of peripheral functions, A to N, is done by writing
to the Peripheral Multiplexing Odd and Even bits in the Peripheral Multiplexing register
(PMUXn.PMUXE/O) of the PORT. The table below describes the peripheral signals multiplexed to the
PORT I/O pins.
Important: Not all signals are available on all devices. Refer to the Configuration Summary for
available peripherals.
