In order to use this module, other parts of the system must be configured correctly, as described
below.
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.
