Data received on appropriate slot: data[19:0] = {Byte2[3:0], Byte1[7:0], Byte0[7:0]}.
Word stored in AC’97 Controller Channel x Receive Holding Register (AC97C_CxRHR)
(Received Data)
Data is read from AC’97 Controller Channel x Receive Holding Register (AC97C_CxRHR) when
Channel x data size is greater than 16 bits and when big-endian mode is enabled (data written to
memory).
Data received on appropriate slot: data[19:0] = {0x0, Byte1[7:0], Byte0[7:0]}.
Halfword stored in AC’97 Controller Channel x Receive Holding Register (AC97C_CxRHR)
(Received Data).
Data is read from AC’97 Controller Channel x Receive Holding Register (AC97C_CxRHR) when
data size is equal to 16 bits and when big-endian mode is enabled.
Data received on appropriate slot: data[19:0] = {0x000, Byte1[1:0], Byte0[7:0]}.Halfword stored
in AC’97 Controller Channel x Receive Holding Register (AC97C_CxRHR) (Received Data)
Data read from AC’97 Controller Channel x Receive Holding Register (AC97C_CxRHR) when
data size is equal to 10 bits and when big-endian mode is enabled.
The problem of variable sample rate can be summarized by a simple example. When passing a
44.1 kHz stream across the AC-link, for every 480 audio output frames that are sent across, 441
of them must contain valid sample data. The new AC’97 standard approach calls for the addition
of “on-demand” slot request flags. The AC‘97 Codec examines its sample rate control register,
the state of its FIFOs, and the incoming SDATA_OUT tag bits (slot 0) of each output frame and
then determines which SLOTREQ bits to set active (low). These bits are passed from the AC97
