Enable 32-byte Buffer (E32B) — R/W.
0 = Disable.
1 = Enable. The Host Block Data register is a pointer into a 32-byte buffer, as opposed to a single
Automatically Append CRC (AAC) — R/W.
0 = Disable.
1 = Enable. The ICH4 automatically appends the CRC. This bit must not be changed during SMBus

SMLINK_CLK_CTL — R/W.
0 = ICH4 drives the SMLINK[0] pin low, independent of what the other SMLINK logic would otherwise
1 = The SMLINK[0] pin is not overdriven low. The other SMLINK logic controls the state of the pin.
SMLINK1_CUR_STS — R/W. This pin returns the value on the SMLINK[1] pin. This allows software
to read the current state of the pin. Default value is dependent on an external signal level.
0 = Low
1 = High
SMLINK0_CUR_STS — RO. This pin returns the value on the SMLINK[0] pin. This allows software to
read the current state of the pin. Default value is dependent on an external signal level.
