Datasheet
DPSLP#
Input
DPSLP# when asserted on the platform causes the processor to transition from the
Sleep State to the Deep Sleep state. In order to return to the Sleep State, DPSLP#
must be deasserted and BCLK[1:0] must be running.
DRDY#
Input/
Output
DRDY# (Data Ready) is asserted by the data driver on each data transfer,
indicating valid data on the data bus. In a multi-common clock data transfer, DRDY#
may be deasserted to insert idle clocks. This signal must connect the appropriate
pins of all processor FSB agents.
DSTBN[3:0]#
Input/
Output
Data strobe used to latch in D[63:0]#.
DSTBP[3:0]#
Input/
Output
Data strobe used to latch in D[63:0]#.
FERR#/PBE#
Output
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.
When FERR#/PBE# is asserted, indicating a break event, it will remain asserted
until STPCLK# is deasserted. For additional information on the pending break
event functionality, including the identification of support of the feature and enable/
disable information, refer to volume 3 of the Intel Architecture Software Developer's
Manual
and the Intel Processor Identification and the CPUID Instruction application
note.
GTLREF
Input
GTLREF determines the signal reference level for AGTL+ input pins. GTLREF
should be set at 2/3 V
CC. GTLREF is used by the AGTL+ receivers to determine if a
signal is a logical 0 or logical 1. Refer to the Mobile Intel
Pentium
4 Processor-M
and Intel
845MP/845MZ Chipset Platform Design Guide
for more information.
HIT#
HITM#
Input/
Output
Input/
Output
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.
