Electrical Specifications
NOTES:
1. Refer to 
 for signal descriptions and termination requirements.
2. BPM[2:0]# and PRDY# are AGTL+ output only signals.
3. 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.

CMOS Signals
CMOS input signals are shown in 
. Legacy output FERR#, IERR# and other non-AGTL+ 
signals (THERMTRIP# and PROCHOT#) utilize 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 at least three BCLKs in order for the chipset to recognize them. See 
 for the DC specifications for the CMOS signal groups.
