BPM[5:0]#
Input/
Output
BPM[5:0]# (Breakpoint Monitor) are breakpoint and performance 
monitor signals. They are outputs from the processor which indicate 
the status of breakpoints and programmable counters used for 
monitoring processor performance. BPM[5:0]# should connect the 
appropriate pins/lands of all processor FSB agents.
BPM4# provides PRDY# (Probe Ready) functionality for the TAP 
port. PRDY# is a processor output used by debug tools to determine 
processor debug readiness.
BPM5# provides PREQ# (Probe Request) functionality for the TAP 
port. PREQ# is used by debug tools to request debug operation of 
the processor.
These signals do not have on-die termination. 
BPRI#
Input
BPRI# (Bus Priority Request) is used to arbitrate for ownership of 
the processor FSB. It must connect the appropriate pins/lands of all 
processor FSB agents. Observing BPRI# active (as asserted by the 
priority agent) causes all other agents to stop issuing new requests, 
unless such requests are part of an ongoing locked operation. The 
priority agent keeps BPRI# asserted until all of its requests are 
completed, then releases the bus by de-asserting BPRI#.
BR0#
Input/
Output
BR0# drives the BREQ0# signal in the system and is used by the 
processor to request the bus. During power-on configuration this 
signal is sampled to determine the agent ID = 0. 
This signal does not have on-die termination and must be 
terminated.
BSEL[2:0]
Output
The BCLK[1:0] frequency select signals BSEL[2:0] are used to 
select the processor input clock frequency. 
 defines the 
possible combinations of the signals and the frequency associated 
with each combination. The required frequency is determined by 
the processor, chipset and clock synthesizer. All agents must 
operate at the same frequency. For more information about these 
signals, including termination recommendations refer to 
COMP8
COMP[3:0]
Analog
COMP[3:0] and COMP8 must be terminated to V
SS 
on the system 
board using precision resistors.
