3. Simulation data shows that these resistor values can range from 10 kΩ to 20 kΩ.
4. Simulation data shows that these resistor values can range from 9 kΩ to 50 kΩ.
5. The pull-down resistors on ACZ_SYNC (AC ‘97) and ACZ_SDOUT (AC ‘97) are enabled during reset and
6. Simulation data shows that these resistor values can range from 10 kΩ to 40 kΩ.
7. The pull-down on this signal (in Intel High Definition Audio mode) is only enabled when in S3
8. Simulation data shows that these resistor values can range from 5.7 kΩ to 28.3 kΩ.
9. The pull-up or pull-down on this signal is only enabled at boot/reset for strapping function.

- The LSO bit (bit 3) in the AC ’97 Global Control Register (D30:F2:2C) is set to 1, or
- Both Function 2 and Function 3 of Device 30 are disabled.

Signal
Tri-state. ICH6 not driving the signal high or low.
ICH6 is driving the signal to a logic 1
ICH6 is driving the signal to a logic 0
Driven to a level that is defined by the function (will be high or low)
ICH6 is driving the signal, but the value is indeterminate.
Clock is toggling or signal is transitioning because function not stopping
The power plane is off, so ICH6 is not driving
