3.

The value of these signals during the active-to-inactive edge of RESET# defines the 
processor configuration options. See 

 for details.

4.

PROCHOT# signal type is open drain output and CMOS input.

.

NOTES:
1.

Signals that do not have R

TT

, nor are actively driven to their high-voltage level.

 

NOTE:
1.

See 

 for more information.

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/de-

asserted for at least eight BCLKs in order for the processor to recognize the proper 

signal state. See 

 for the DC specifications. See 

 for additional 

timing requirements for entering and leaving the low power states.
