Status Field
For a read cycle, the returned data is preceded by one byte of status. The following
table shows how the status byte bits are defined.
Unsupported Access Addresses
It is possible for an SMBus master to program an unsupported bit combination into the
ADDR registers. The MCH does not support such usage, and may not gracefully
terminate such accesses.
SMB Transaction Pictographs
The Intel 5000P Chipset MCH SMBus target interface is targeted to enterprise domains.
The enterprise domain is an extension of the original SMBus desktop domain. The
following drawings are included to describe the SMBus enterprise transactions.
