waveform. Also, the Controller receives the stereo PCM data and the mono Mic data
from the Codec and then stores them in the memories. This chapter describes the
programming model for the AC97 Controller Unit. The information in this chapter
requires an understanding of the AC97 revision 2.0 specifications.
Note: The AC97 Controller and the IIS Controller must not be used at the same time.
Features:
The following shows the functional block diagram of the S3C2443 AC97 Controller.
The AC97 signals form the AClink, which is a point-to-point synchronous serial
interconnect that supports full-duplex data transfers. All digital audio streams and
command/status information are communicated over the AC-link.
Independent channels for stereo PCM In, stereo PCM Out, mono MIC In.
DMA-based operation and interrupt based operation.
All of the channels support only 16-bit samples.
Variable sampling rate AC97 Codec interface (48 KHz and below).
16-bit, 16 entry FIFOs per channel
Only Primary CODEC support
