MIX

Mono Output Select.

0 = Mix.

1 = Mic.

3D

Phat Stereo Enhancement.

0 = Phat Stereo is off.

1 = Phat Stereo is on.

POP

PCM Output Path. The POP bit controls the optional PCM out 3D bypass path (the pre- and post-

3D PCM outpaths are mutually exclusive).

0 = Pre-3D.

1 = Post-3D.

The register should be read before writing to generate a mask for only the bit(s) that need to be changed. The

default value is 0000h.

Ready Bits: The ready bits are read only, writing to REF, ANL, DAC, ADC will have no effect. These bits indi-

cate the status for the AD1819B subsections. If the bit is a one then that subsection is “ready.” Ready is defined as

the subsection able to perform in its nominal state.

ADC

ADC section ready to transmit data.

DAC

DAC section ready to accept data.

ANL

Analog gainuators, attenuators, and mixers ready.

REF

PR [5:0]

Power-Down Bits. Bits 0 and 1 are to be used individually rather than in combination with each other. The last bit

PR3 can be used in combination with PR2 or by itself.
