Default value: 0

DACMSK = 0

Mask disable (default)

DACMSK = 1

Mask DIN to BPZ level

The DACMSK bit is used to mask DIN to BPZ level. The analog outputs from DAC is forced to BPZ level

immediately. Larger noise may be generated by this control.

Default value: 000 (2 audio channels without pre-emphasis)

The AFI[5:3] bits control bits[5:3] of channel status bits in compliance with IEC958.

Default value: 0 (Asserted)

The COPY bit controls bit[2] of channel status bits in compliance with IEC958.

Default value: 0 (PCM)

The AUDIO bit controls bit[1] of channel status bits in compliance with IEC958.

Default value: 0

DITMSK = 0

Mask disable (default)

DITMSK = 1

Force DOUTS to encoded ZERO status

The DITMSK bit forces only aux and audio sample words on DOUTS to encoded ZERO status. As for validity

and channel status bits, the values in the register are output.
