BPM[2:1]#
BPM[3,0]#
Output
Input/
Output
BPM[3:0]# (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[3:0]# should connect the
appropriate pins of all processor FSB agents.This includes debug or
performance monitoring tools.
Please contact your Intel representative for more detailed
information.
BPRI#
Input
BPRI# (Bus Priority Request) is used to arbitrate for ownership of
the FSB. It must connect the appropriate pins of both FSB agents.
Observing BPRI# active (as asserted by the priority agent) causes
the other agent 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 deasserting BPRI#.
BR0#
Input/
Output
BR0# is used by the processor to request the bus. The arbitration is
done between the processor (Symmetric Agent) and the Mobile
Intel 945 Express Chipset family (High Priority Agent).
BSEL[2:0]
Output
BSEL[2:0] (Bus Select) are used to select the processor input clock
frequency. Table 3 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. The
processor operates at 667-MHz or 533-MHz system bus frequency
(166-MHz or 133-MHz BCLK[1:0] frequency, respectively).
COMP[3:0]
Analog
COMP[3:0] must be terminated on the system board using
precision (1% tolerance) resistors. Please contact your Intel
representative for more implementation details.
