NOTES:  

1. 

Refer to Chapter 

4 for signal descriptions and termination requirements. 

2. 

In processor systems where there is no debug port implemented on the system board, 

these signals are used to support a debug port interposer. In systems with the debug 

port implemented on the system board, these signals are no connects. 

3. 

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

CMOS input signals are shown in Table 5. Legacy output FERR#, IERR# and other 

non- AGTL+ signals (THERMTRIP# and PROCHOT#) use Open Drain output buffers. 

These signals do not have setup or hold time specifications in relation to BCLK [1:0]. 

However, all of the CMOS signals are required to be asserted for more than 5 BCLKs 
for the processor to recognize them. See Section 

3.10 for the DC specifications for the 

CMOS signal groups. 

Table 6 specifies absolute maximum and minimum ratings. Within functional operation 

limits, functionality and long-term reliability can be expected. 

At conditions outside functional operation condition limits, but within absolute 

maximum and minimum ratings, neither functionality nor long term reliability can be 

expected. If a device is returned to conditions within functional operation limits after 

having been subjected to conditions outside these limits, but within the absolute 

maximum and minimum ratings, the device may be functional, but with its lifetime 

degraded depending on exposure to conditions exceeding the functional operation 

condition limits. 

At conditions exceeding absolute maximum and minimum ratings, neither functionality 

nor long term reliability can be expected. Moreover, if a device is subjected to these 

conditions for any length of time then, when returned to conditions within the 

functional operating condition limits, it will either not function or its reliability will be 

severely degraded.  

Although the processor contains protective circuitry to resist damage from static 

electric discharge, precautions should always be taken to avoid high static voltages or 

electric fields.
