ICH7 Family Datasheet
AC ’97 Audio I/O Space (D30:F2)
The AC ’97 I/O space includes Native Audio Bus Master registers and Native Mixer
registers. For the ICH7, the offsets are important as they will determine bits 1:0 of the
TAG field (codec ID).
Audio Mixer I/O space can be accessed as a 16-bit field only since the data packet
length on
AC-link is a word. Any S/W access to the codec will be done as a 16-bit access starting
from the first active byte. In case no byte enables are active, the access will be done at
the first word of the qWord that contains the address of this request.
