Datasheet
DINV[3:0]#
Input/
Output
DINV[3:0]# (Data Bus Inversion) are source synchronous and
indicate the polarity of the D[63:0]# signals. The DINV[3:0]#
signals are activated when the data on the data bus is inverted. The
bus agent will invert the data bus signals if more than half the bits,
within the covered group, would change level in the next cycle.
DPRSTP#
Input
DPRSTP# when asserted on the platform causes the processor to
transition from the Deep Sleep State to the Deeper Sleep state. In
order to return to the Deep Sleep State, DPRSTP# must be
deasserted. DPRSTP# is driven by the Intel ICH7M chipset.
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. DPSLP# is
driven by the ICH7M chipset.
DPWR#
Input
DPWR# is a control signal from the Mobile Intel 945 Express
Chipset family used to reduce power on the processor data bus
input buffers.
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 both 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]#.
