NOTES:
1. Refer to
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
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 processor to recognize them.
