51.5.1 I/O Lines

Using the I²S I/O lines requires the I/O pins to be configured.

The I²S pins may be multiplexed with I/O Controller lines. The user must first program the I/O Controller to assign the desired I²S pins to their peripheral function. If the I²S I/O lines are not used by the application, they can be used for other purposes by the I/O Controller. It is required to enable only the I²S inputs and outputs actually in use.
