S/PDIF Output
Audio Input Bit Clock. The CS98000 can be programmed to
use the Audio Output function’s internally generated bit
clock, in which case this pin is not required.
Audio Input Left/Right Clock. The CS98000 can be pro-
grammed to use the Audio Output function’s internally gen-
erated LR clock, in which case this pin is not required.
Audio Input Data from Serial ADC.
Serial Data Input from Modem CODEC
Serial Data Output to Modem CODEC
Reset Output to Modem CODEC
Serial Bit Clock input from Modem CODEC
Frame Sync, output when CS98000 is master, input when
CODEC is master.

This serial interface could be used either as a sec-
ond PCM CODEC interface or as an AC97 serial
link to an AC97 compliant CODEC. This could
control a modem, or a second set of audio channels.
