I/O Lines Description
The output pins used for the output bitstream from the Audio Bitstream DAC may be multiplexed
with PIO lines.
Before using the Audio Bitstream DAC, the PIO controller must be configured in order for the
Audio Bitstream DAC I/O lines to be in Audio Bitstream DAC peripheral mode.
The PB-bus clock to the Audio Bitstream DAC is generated by the power manager. Before using
the Audio Bitstream DAC, the programmer must ensure that the Audio Bitstream DAC clock is
enabled in the power manager.
