Stereo CODEC Interface

The Z893XX DSP product family CODEC interface pro-

vides direct connection to other CODECs for master or

slave modes, supporting 64 bits of transmission data (16

bits right channel, 16 bits left channel, and 32 bits of con-

figuration information). This configuration information con-

sists of input gain, input MUX, output attenuation, ADC

clipping, and mute and error functions of the CODECs.

A key feature of the Z893XX DSP product family is that it

adapts easily to other stereo CODECs, including Crystal

Semiconductor's CS4215 and CS4216 devices (Figure

31).

The 64 bits of data transferred from the CODEC are placed

in four registers, EXT5-1, 5-2, 6-1, and 6-2 (Figure 32 ).
