bit[11]
For normal operation (MPEG-decoding and D/A conversion), both, the DSP
core and the audio codec have to be enabled after the power-up procedure.
The DSP can be left off if an audio signal is routed from the analog inputs to
the analog outputs (set bit[15] in codec register 00 0F
hex
). The audio codec
can be left off if the DSP uses digital inputs and outputs only.
