Data received on appropriate slot: data[19:0] = {Byte2[3:0], Byte1[7:0], Byte0[7:0]}.
Word stored in AC97 Controller Channel x Receive Holding Register (AC97C_CxRHR)
(Received Data)
Data is read from AC97 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 AC97 Controller Channel x Receive Holding Register (AC97C_CxRHR)
(Received Data).
Data is read from AC97 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 AC97 Controller Channel x Receive Holding Register (AC97C_CxRHR) (Received Data)
Data read from AC97 Controller Channel x Receive Holding Register (AC97C_CxRHR) when
data size is equal to 10 bits and when big-endian mode is enabled.
