0 = ICH8 will drive the SMLINK0 pin low, independent of what the other SMLINK logic
1 = The SMLINK0 pin is not overdriven low. The other SMLINK logic controls the state
SMLINK1_CUR_STS — RO. This read-only bit has a default value that is dependent on
an external signal level. This pin returns the value on the SMLINK1 pin. This allows
software to read the current state of the pin.
