companion codecs through a digital serial link called the AC-link. All digital audio/
modem streams and command/status information is communicated over the AC-link.
The AC-link is a bi-directional, serial PCM digital stream. It handles multiple input and
output data streams, as well as control register accesses, employing a time division
multiplexed (TDM) scheme. The AC-link architecture provides for data transfer through
individual frames transmitted in a serial fashion. Each frame is divided into 12 outgoing
and 12 incoming data streams, or slots. The architecture of the Intel
AC-link allows a maximum of three codecs to be connected.

The AC'97 modem controller is a separate PCI function. However, the AC'97 modem
controller is implemented in the same logical unit as the AC'97 audio functions. There
are registers declared in the audio function which contain modem information - these
registers are also visible in the modem IO space, but are implemented as a single
register.
The AC-link consists of a five signal interface between the controller and codec.
