DEFAULT
Controls whether ADC data appears in ‘right’ or ‘left’
phases of FRAME clock:
0=ADC data appear in ‘left’ phase of FRAME
1=ADC data appears in ‘right’ phase of FRAME
Reserved
Reserved
Digital loopback function
0=No DAC loopback
1=Loopback enabled, DAC data input is fed directly
into ADC data output.
8 Bit Word Length for companding
0=Word Length controlled by WL
1=8 bits
DAC companding
00=off
01=reserved
10=µ-law

Digital loopback function
0=No ADC loopback
1=Loopback enabled, ADC data output is fed directly
into DAC data input.
Reserved
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)
