6300ESB ICH
AC’97 Modem I/O Space (D31:F6)
In the case of split codec implementation, accesses to the modem mixer registers in
different codecs are differentiated by the controller by using address offsets 00h - 7Fh
for the primary codec and address offsets 80h - FEh for the secondary codec.
shows the register addresses for the modem mixer registers.
Configuration
The Global Control (GLOB_CNT) and Global Status (GLOB_STA) registers are aliased to
the same global registers in the audio and modem I/O space. Therefore a read/write to
these registers in either audio or modem I/O space affects the same physical register.
S/W could access these registers as bytes, word, or dWord quantities, but reads must
not cross dWord boundaries.
These registers exist in I/O space and reside in the AC ‘97 controller. The two channels,
Modem in and Modem out, each have their own set of Bus Mastering registers. The
following register descriptions apply to both channels. The naming prefix convention
