47.5.1 I/O Lines

The I2SMCC pins may be multiplexed with I/O Controller lines. The user must first program the PIO Controller to assign the required I2SMCC pins to their peripheral function. If the I2SMCC I/O lines are not used by the application, they can be used for other purposes by the PIO Controller. The user must enable the I2SMCC inputs and outputs that are used.
