2.6.2
CMOS and Open Drain Signals
Legacy input signals such as A20M#, IGNNE#, INIT#, SMI#, and STPCLK# use CMOS
input buffers. All of the CMOS and Open Drain signals are required to be asserted/
deasserted for at least four BCLKs for the processor to recognize the proper signal
state. See
for additional timing
requirements for entering and leaving the low power states.
2.6.3
Processor DC Specifications
The processor DC specifications in this section are defined at the processor core (pads)
unless otherwise stated. All specifications apply to all frequencies and cache sizes
unless otherwise stated.
