Controls simultaneous update of all Attenuation Latches
Digital Attenuation control for all DAC channels in 0.5dB steps.
See Table 23

ADC Mute select
ADC oversample rate select
ADC high-pass filter disable:
ADC Rate Control (only used when the S/PDIF Transmitter is the
only interface sourcing the ADC)
VMID Impedance Selection
S/PDIF Transmitter Data Source
Only used if TXSRC==00. Overwrites the ‘through-path’ Channel
Bit with values determined by the channel-bit control registers.
S/PDIF Through Mode Control
0 = Normal Operation
1 = mute ADC left
0 = Normal Operation
1 = mute ADC right
0 = Normal Operation
1 = mute both ADC channels
0 = high-pass filter enabled
1 = high-pass filter disabled
0 = Store RDA3 in intermediate latch (no change to output)
1 = Apply RDA3 and update attenuation on all channels
0 = Store gain in intermediate latch (no change to output)
1 = Apply gain and update attenuation on all channels
0 = 128/64 x oversampling
1 = 64/32 x oversampling

0 = Channel data equal to recovered channel data.
1 = Channel data taken from channel status registers.
0 = SPDIFOP pin sources output of S/PDIF Transmitter
1 = SPDIFOP pins sources output of S/PDIF IN Mux
0 = High impedance, power saving
1 = Low impedance, fast power-on
00 = S/PDIF received data (see REAL_THROUGH)
01 = ADC digital output data.
10 = Secondary Audio Interface
