Section
For example, if it were desired to use only the 12 MSBits of the A/D converter in
Figure
LEFT[15:4] being set with data bits 0..11 and LEFT[3:0] being set equal to zero.
RIGHT[15:4] is set with data bits 32..43 and RIGHT[3:0] is set to zero.
Similarly, if it was desired to use only the 12 MSBits, but send 32 bit samples to
memory, use the settings of
LEFT[31:20] being set with data bits 0...11 and LEFT[20:0] being set equal to zero.
RIGHT[31:4] is set with data bits 32...43 and RIGHT[20:0] is set to zero.

S A/D Converter (Format 2 SWS)
SAA7366 is serial master.
SCK set to OSCLK/4 (not needed since SER_MASTER = 0).
Serial frame length of 64 bits (not needed since SER_MASTER = 0)
Frame starts with negative WS.
Take a sample of each serial frame.
Don’t care (Every frame is valid).
Bit position 0 is MSB of left channel and will go to LEFT[15].
Bit position 32 is MSB of right channel and will go to RIGHT[15].
MSB first
Stop with LEFT/RIGHT[0].
