TRDY# (Target Ready) is asserted by the target to indicate that it is ready to
receive a write or implicit writeback data transfer. TRDY# must connect the
appropriate pins of both system bus agents.
TRST# (Test Reset) resets the Test Access Port (TAP) logic. TRST# must be
driven low during power on Reset. Please refer to the ITP700 Debug Port

VID[5:0] (Voltage ID) pins are used to support automatic selection of power
supply voltages (Vcc). Unlike some previous generations of processors, these
are CMOS signals that are driven by the Intel Pentium M processor. The voltage
supply for these pins must be valid before the VR can supply Vcc to the
processor. Conversely, the VR output must be disabled until the voltage supply
for the VID pins becomes valid. The VID pins are needed to support the
processor voltage specification variations. See

itself.
