6.1.12 Extended Audio ID (Index 28h)

ID[1:0]

Codec configuration ID. Primary is 00; Secondary is 01,10,or 11. This is a reflection of the ID[1:0]# con-

figuration pins. The state of the ID# pins are determined at power-up and are the inverse of the ID bits

in this register.

LDAC

PCM LFA DAC. Indicates a LFE DAC is supported.

SDAC

PCM Surround DAC. Indicates a Surround DAC is supported.

CDAC

PCM Center DAC. Indicates a Center DAC is supported.

VRA

Variable Rate Audio. This bit is clear indicating variable sample rates are not supported.

Read-only data Mode 0,1,2

x000h. Where x is determined by the state of ID[1:0] input pins.

Mode 3

x1C0h.
