Specifies if the audio encoder is enabled.
If the audio encoder is disabled, no audio data
will be inserted in the output stream.
defines the audio input format
In master mode, SAA6752HS delivers the bit
clock and word select signal. In slave mode,
SAA6752HS receives the bit clock and word
select signal. Remark: If I
to output mode (VES + AES output stream
mode) then SAA6752HS is fixed to master
mode.
