Description
Reserved.
When set, the Host Block Data register is a pointer into a
32-byte buffer, as opposed to a single register. This enables
the block commands to transfer or receive up to 32 bytes
®
before the Intel 6300ESB ICH generates an interrupt.
®
When set, the Intel 6300ESB ICH will automatically append
the CRC. This bit must not be changed during SMBus
transactions, or undetermined behavior will result
Attribute:
Description
Reserved.
This Read/Write bit has a default of 1.
®
0 = The Intel 6300ESB ICH will drive the SMLINK[0] pin
low, independent of what the other SMLINK logic would
otherwise indicate for the SMLINK[0] pin.
1 = The SMLINK[0] pin is not overdriven low. The other
SMLINK logic controls the state of the pin.
This read-only bit has a default value that is dependent on an
external signal level. This pin returns the value on the
SMLINK[1] pin. It will be '1' to indicate high, '0' to indicate
low. This allows software to read the current state of the pin.
