Selects between stereo and mono DAC operation:
0=Stereo device operation
1=Mono device operation. DAC data appears in
‘left’ phase of LRC
Reserved
Companding Control 8-bit mode
0=off
1=device operates in 8-bit mode
DAC companding
00=off (linear mode)
01=reserved
10=µ-law
11=A-law
ADC companding
00=off (linear mode)
01=reserved
10=µ-law
11=A-law
Digital loopback function
0=No loopback
1=Loopback enabled, ADC data output is fed
directly into DAC data input.
Controls the source of the clock for all internal
operation:
0=MCLK
1=PLL output
Sets the scaling for either the MCLK or PLL clock
output (under control of CLKSEL)

Configures the BCLK output frequency, for use
when the chip is master over BCLK.
000=divide by 1 (BCLK=MCLK)
001=divide by 2 (BCLK=MCLK/2)
010=divide by 4
011=divide by 8
100=divide by 16
101=divide by 32

Reserved
Sets the chip to be master over LRC and BCLK
0=BCLK and LRC clock are inputs
1=BCLK and LRC clock are outputs generated by
the WM8976 (MASTER)
