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.
word, and D-word quantities. The software must always make register accesses on natural
boundaries (i.e. D-word accesses must be on D-word 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.
