Stop-Grant State

When the STPCLK# pin is asserted, the Stop-Grant state of the processor is entered 20 
bus clocks after the response phase of the processor issued Stop Grant Acknowledge 
special bus cycle. Once the STPCLK# pin has been asserted, it may only be deasserted 
once the processor is in the Stop Grant state. All processor cores will enter the Stop-
Grant state once the STPCLK# pin is asserted. Additionally, all processor cores must be 
in the Stop Grant state before the deassertion of STPCLK#.

Since the AGTL+ signal pins receive power from the front side bus, these pins should 
not be driven (allowing the level to return to V

TT

) for minimum power drawn by the 

termination resistors in this state. In addition, all other input pins on the front side bus 
should be driven to the inactive state.

BINIT# will not be serviced while the processor is in Stop-Grant state. The event will be 
latched and can be serviced by software upon exit from the Stop Grant state.

RESET# will cause the processor to immediately initialize itself, but the processor will 
stay in Stop-Grant state. A transition back to the Normal state will occur with the de-
assertion of the STPCLK# signal.

A transition to the Grant Snoop state will occur when the processor detects a snoop on 
the front side bus (see 

Section 7.2.4.1

).
