34.5 Product Dependencies
In order to use this module, other parts of the system must be configured correctly, as described
below.
34.5.1 I/O Lines
The output pins used for the output bitstream from the Audio Bitstream DAC may be multiplexed
with IO lines.
Before using the Audio Bitstream DAC, the I/O Controller must be configured in order for the
Audio Bitstream DAC I/O lines to be in Audio Bitstream DAC peripheral mode.
