FERR#/PBE#
O
FERR#/PBE# (floating-point error/pending break event) is a multiplexed signal and 
its meaning is qualified by STPCLK#. When STPCLK# is not asserted, FERR#/PBE# 
indicates a floating-point error and will be asserted when the processor detects an 
unmasked floating-point error. When STPCLK# is not asserted, FERR#/PBE# is similar 
to the ERROR# signal on the Intel 387 coprocessor, and is included for compatibility 
with systems using MS-DOS*-type floating-point error reporting. When STPCLK# is 
asserted, an assertion of FERR#/PBE# indicates that the processor has a pending 
break event waiting for service. The assertion of FERR#/PBE# indicates that the 
processor should be returned to the Normal state. For additional information on the 
pending break event functionality, including the identification of support of the feature 
and enable/disable information, refer to Vol. 3 of the Intel Architecture Software 
Developer’s Manual and the Intel Processor Identification and the CPUID Instruction 
application note.

FORCEPR#
I
The FORCEPR# (force power reduction) input can be used by the platform to cause 
the Dual-Core Intel
® 
Xeon
® 
Processor 5100 Series  to activate the Thermal Control 
Circuit (TCC).
GTLREF_ADD
I
GTLREF_ADD determines the signal reference level for AGTL+ address and common 
clock input lands. GTLREF_ADD is used by the AGTL+ receivers to determine if a 
signal is a logical 0 or a logical 1. 
GTLREF_DATA
I
GTLREF_DATA determines the signal reference level for AGTL+ data input lands. 
GTLREF_DATA is used by the AGTL+ receivers to determine if a signal is a logical 0 or 
a logical 1. 
HIT#
HITM#
I/O
I/O
HIT# (Snoop Hit) and HITM# (Hit Modified) convey transaction snoop operation 
results. Any FSB agent may assert both HIT# and HITM# together to indicate that it 
requires a snoop stall, which can be continued by reasserting HIT# and HITM# 
together.
3
IERR#
O
IERR# (Internal Error) is asserted by a processor as the result of an internal error. 
Assertion of IERR# is usually accompanied by a SHUTDOWN transaction on the 
processor FSB. This transaction may optionally be converted to an external error 
signal (e.g., NMI) by system core logic. The processor will keep IERR# asserted until 
the assertion of RESET#.
This signal does not have on-die termination.

IGNNE#
I
IGNNE# (Ignore Numeric Error) is asserted to force the processor to ignore a numeric 
error and continue to execute noncontrol floating-point instructions. If IGNNE# is 
deasserted, the processor generates an exception on a noncontrol floating-point 
instruction if a previous floating-point instruction caused an error. IGNNE# has no 
effect when the NE bit in control register 0 (CR0) is set.
IGNNE# is an asynchronous signal. However, to ensure recognition of this signal 
following an I/O write instruction, it must be valid along with the TRDY# assertion of 
the corresponding I/O write bus transaction.
