NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. All AC timings for the Asynch GTL+ signals are referenced to the BCLK0 rising edge at Crossing Voltage. All
Asynch GTL+ signal timings are referenced at GTLREF. PWRGOOD is referenced o the BCLK0 rising edge
at 0.5*VCC.
3. These signals may be driven asynchronously.
4. Refer to the PWRGOOD definition for more details regarding the behavior of this signal.
5. Length of assertion for PROCHOT# does not equal internal clock modulation time. Time is allocated after the
assertion and before the deassertion of PROCHOT# for the processor to complete current instruction
execution.
6. See
Section 7.1
for additional timing requirements for entering and leaving the low power states.
NOTES:
1. Before the deassertion of RESET#.
2. After clock that deasserts RESET#.
