Selects de-emphasis response/source

0 - De-emphasis off

1 - De-emphasis on 32 kHz

2 - De-emphasis on 44.1 kHz

3 - De-emphasis on 48 kHz

4 - De-emphasis pin 32 kHz

5 - De-emphasis pin 44.1 kHz

6 - De-emphasis pin 48 kHz

7 - S/PDIF receiver channel status bits

DEM24

Process AUX data LSBs

0 - All received data bits (24 max) are processed

1 - Top 20 bits processed with De-emphasis filter. 4 AUX LSBs are passed unchanged.

MOH

Mute On Hold

0 - Extended Hold (16 frames) mutes DAC outputs

1 - DACs not muted

UMV

Unmute on Valid Data

0 - DACs unmute when ERROR is removed

1 - DACs must be unmuted in DAC control byte after ERROR is removed.

HPC

HOLD/RUBIT Pin Control

0 - HOLD/RUBIT is an input (HOLD)

1 - HOLD/RUBIT is an output (RUBIT)

CSP

Channel Status output to pins.

0 - Analog inputs to pins. AIN2R, AIN2L, AIN3R, AIN3L

1 - Channel status to pins. (This forces AIS1/0=0)

This register defaults to 00h.
