Land Listing and Signal Descriptions

DEFER#

Input

DEFER# is asserted by an agent to indicate that a transaction

cannot be ensured in-order completion. Assertion of DEFER# is

normally the responsibility of the addressed memory or input/

output agent. This signal must connect the appropriate pins/lands

of all processor FSB agents.

DPRSTP#

Input

DPRSTP#, when asserted on the platform, causes the processor to

transition from the Deep Sleep State to the Deeper Sleep state. To

return to the Deep Sleep State, DPRSTP# must be deasserted. Use

of the DPRSTP# pin, and corresponding low power state, requires

chipset support and may not be available on all platforms.

NOTE:

Some processors may not have the Deeper Sleep State

enabled, refer to the Specification Update for specific sku

and stepping guidance.

DPSLP#

Input

DPSLP#, when asserted on the platform, causes the processor to

transition from the Sleep State to the Deep Sleep state. To return

to the Sleep State, DPSLP# must be deasserted. Use of the

DPSLP# pin, and corresponding low power state, requires chipset

support and may not be available on all platforms.

NOTE:

Some processors may not have the Deep Sleep State

enabled, refer to the Specification Update for specific

proceswor and stepping guidance.

DRDY#

Input/

Output

DRDY# (Data Ready) is asserted by the data driver on each data

transfer, indicating valid data on the data bus. In a multi-common

clock data transfer, DRDY# may be de-asserted to insert idle

clocks. This signal must connect the appropriate pins/lands of all

processor FSB agents.

DSTBN[3:0]#

Input/

Output

DSTBN[3:0]# are the data strobes used to latch in D[63:0]#.

DSTBP[3:0]#

Input/

Output

DSTBP[3:0]# are the data strobes used to latch in D[63:0]#.

FC0/BOOTSELECT

Other

FC0/BOOTSELECT is not used by the processor. When this land is

tied to Vss previous processors based on the Intel NetBurst

microarchitecture should be disabled and prevented from booting.

FCx

Other

FC signals are signals that are available for compatibility with other

processors.
