NOTES:
1.
2.
Not 100% tested. Specified by design characterization.
All AC timings for the CMOS signals are referenced to the BCLK rising edge at 0.7 V at the processor edge fingers. All
CMOS signal timings (address bus, data bus, etc.) are referenced at 1.25 V at the processor edge fingers.
These signals may be driven asynchronously, but must be driven synchronously in FRC mode.
Valid delay timings for these signals are specified to 2.5 V +5%.. See Table 3 for pull-up resistor values.
To ensure recognition on a specific clock, the setup and hold times with respect to BCLK must be met.
INTR and NMI are only valid during APIC disable mode. LINT[1:0]# are only valid during APIC enabled mode.
When driven inactive or after Vcc
CORE
, Vcc
L2
and BCLK become stable.

For a Reset, the clock ratio defined by these signals must be a safe value (their final or lower multiplier) within this delay
unless PWRGOOD is being driven inactive.
