High Definition Audio Controller Registers (D27:F0)

Controller Registers (D27:F0)
The Intel High Definition Audio controller resides in PCI Device 27, Function 0 on bus 0.
This function contains a set of DMA engines that are used to move samples of digitally
encoded data between system memory and external codecs.
All registers in this function (including memory-mapped registers) must be addressable
in byte, word, and DWord quantities. The software must always make register accesses
on natural boundaries (i.e., DWord accesses must be on DWord boundaries; word
accesses on word boundaries, etc.) In addition, the memory-mapped register space
must not be accessed with the LOCK semantic exclusive-access mechanism. If software
attempts exclusive-access mechanisms to the Intel High Definition Audio memory-
mapped space, the results are undefined.
Users interested in providing feedback on the Intel High Definition Audio specification
or planning to implement the Intel High Definition Audio specification into a future
product will need to execute the Intel
Agreement. For more information, contact [e-mail].
