The ac97 protocol decoder can decode the AC'97 signal between the digital controller and the audio or modem codec (which contains the audio output / analog components of the architecture).
AC'97 defines a high-quality, 16- or 20-bit audio architecture with 5.1 surround sound support for the PC. AC'97 supports a 96 kHz sampling rate at 20-bit stereo resolution and a 48 kHz sampling rate at 20-bit stereo resolution for multichannel recording and playback.
Status
Bits are annotated with the correct bit number. Slots are correctly annotated.
