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 inverts 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
82801HBM ICH8M I/O Controller Hub-based chipset.

DPWR#
Input/
Output
DPWR# is a control signal used by the chipset to reduce power on the processor
data bus input buffers. The processor drives this pin during dynamic FSB frequency
switching

.
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.
