Controls whether DAC data appears in ‘right’ or
‘left’ phases of LRC clock:
0=DAC data appear in ‘left’ phase of LRC
1=DAC data appears in ‘right’ phase of LRC
Controls whether ADC data appears in ‘right’ or
‘left’ phases of LRC clock:
0=ADC data appear in ‘left’ phase of LRC
1=ADC data appears in ‘right’ phase of LRC
Selects between stereo and mono device
operation:
0=Stereo device operation
1=Mono device operation. 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

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)
