This BAR creates 512 bytes of memory space to signify the base address of the register
space. The lower 256 bytes of this space map to the same registers as the 256-byte I/
O space pointed to by NAMBAR. The lower 384 bytes are divided as follows:

128 bytes for the primary codec (offsets 00 – 7Fh)
128 bytes for the secondary codec (offsets 80h – FFh)
128 bytes for the tertiary codec (offsets 100h – 17Fh).
128 bytes of reserved space (offsets 180h – 1FFh), returning all ‘0’.
Reserved. Hardwired to ‘0’.
These bits are used in the I/O space decode of the Native
Audio Bus Mastering interface registers. The number of upper
bits that a device actually implements depends on how much
of the address space the device will respond to. For AC’97 bus
mastering, the upper 16 bits are hardwired to ‘0’, while bits
15:6 are programmable. This configuration yields a maximum
I/O block size of 64 bytes for this base address.
Reserved. Read as ‘0’s.
This read-only bit defaults to ’0’ and flips to ’1’ if bit ’0’ of
offset 41h is set. When this bit is set to ‘1’, it indicates a
request for I/O space.
Lower 32 bits of the 512-byte memory offset to use for
decoding the primary, secondary, and tertiary codec’s mixer
spaces.
