SMBus Interfaces Description
The Intel 5000P Chipset MCH provides six fully functional System Management Bus
(SMBus) Revision 2.0 compliant target interfaces. These interfaces are used to support
platform level operations such as FB-DIMM memory Serial Presence Detect, PCI Hot-
Plug, and configuration of platform devices. Each of these interfaces have dedicated
uses as shown in

Control logic on the platform must ensure that there
are at least 2 mS of stable power before PwrGd is
asserted.
Intel 631xESB/632xESB I/O Controller Hub enforces
delay between detecting PwrGd asserted and
releasing PCIRST# (note that Intel 631xESB/
632xESB I/O Controller Hub PCIRST# is directly
connected to MCH RSTIN#).
MCH waits for a common rising edge on all internal
clocks, then releases core reset(s).
MCH enforces delay between RSTIN# and
FSBxRESET# deassertion. ESI handshake is
incremental to the timer.
