Features

state. Snoop events that occur while in Sleep state or during a transition into or out of

Sleep state will cause unpredictable behavior. Any transition on an input signal before

the processor has returned to the Stop-Grant state will result in unpredictable behavior.

If RESET# is driven active while the processor is in the Sleep state, and held active as

specified in the RESET# pin specification, then the processor will reset itself, ignoring

the transition through the Stop-Grant state.

If RESET# is driven active while the processor is in the Sleep state, the SLP# and

STPCLK# signals should be deasserted immediately after RESET# is asserted to ensure

the processor correctly executes the Reset sequence.

While in the Sleep state, the processor is capable of entering an even lower power

state, the Deep Sleep state, by asserting the DPSLP# pin (See

Section 6.2.6

). While

the processor is in the Sleep state, the SLP# pin must be deasserted if another

asynchronous FSB event needs to occur. PECI is not available and will not respond

while in the Sleep State.

6.2.6

Deep Sleep State

The Deep Sleep state is entered through assertion of the DPSLP# pin while in the Sleep

state. BCLK may be stopped during the Deep Sleep state for additional platform level

power savings. BCLK stop/restart timings on appropriate chipset-based platforms with

the CK505 clock chip are as follows:

•

Deep Sleep entry:

the system clock chip may stop/tristate BCLK within two BCLKs

of DPSLP# assertion. It is permissible to leave BCLK running during Deep Sleep.

•

Deep Sleep exit:

the system clock chip must drive BCLK to differential DC levels

within 2-3 ns of DPSLP# de-assertion and start toggling BCLK within 10 BCLK

periods.

To re-enter the Sleep state, the DPSLP# pin must be deasserted. BCLK can be restarted

after DPSLP# de-assertion as described above. A period of 15 microseconds (to allow

for PLL stabilization) must occur before the processor can be considered to be in the

Sleep state. Once in the Sleep state, the SLP# pin must be deasserted to re-enter the

Stop-Grant state.

While in the Deep Sleep state the processor is incapable of responding to snoop

transactions or latching interrupt signals. No transitions of signals are allowed on the

FSB while the processor is in the Deep Sleep state. When the processor is in the Deep

Sleep state it will not respond to interrupts or snoop transactions. Any transition on an

input signal before the processor has returned to the Stop-Grant state will result in

unpredictable behavior. PECI is not available and will not respond while in the Deep

Sleep State.

6.2.7

Deeper Sleep State

The Deeper Sleep state is similar to the Deep Sleep state but the core voltage is

reduced to a lower level. The Deeper Sleep state is entered through assertion of the

DPRSTP# pin while in the Deep Sleep state. Exit from Deeper Sleep is initiated by

DPRSTP# de-assertion. PECI is not available and will not respond while in the Deeper

Sleep State.
