Connects between the processor and the ICH7-M. Assertion of
THERMTRIP# (Thermal Trip) indicates the (G)MCH junction
temperature has reached a level beyond which damage may
occur. Upon assertion of THERMTRIP#, the (G)MCH will shut off
its internal clocks (thus halting program execution) in an attempt
to reduce the (G)MCH core junction temperature. To protect
(G)MCH, its core voltage (Vcc) must be removed following the
assertion of THERMTRIP#. Once activated, THERMTRIP#
remains latched until RSTIN# is asserted. While the assertion of
the RSTIN# signal will deassert THERMTRIP#, if the (G)MCH’s
junction temperature remains at or above the trip level,
THERMTRIP# will again be asserted.
Host Reference Voltage:
Reference voltage input for the Data, Address, and Common
clock signals of the host AGTL+ interface.
Host X RCOMP:
Used to calibrate the host AGTL+ I/O buffers.
This signal is powered by the host interface termination rail
(
Host X SCOMP:
Slew rate compensation for the host interface.
Host X Voltage Swing:
These signals provide reference voltages used by the HXRCOMP
circuits.
Host Y RCOMP:
Used to calibrate the host AGTL+ I/O buffers.
Host Y SCOMP:
Slew rate compensation for the host interface.
Host Y Voltage Swing:
These signals provide reference voltages used by the HYRCOMP
circuitry.
