    ... Other THERMTRIP# Output TMS Input ® ® Intel Pentium M Processor Datasheet Package Mechanical Specifications and Pin Information Description SLP# (Sleep), when asserted in Stop-Grant state, causes the processor to enter the Sleep state. During Sleep state, the processor stops providing internal clock signals to all units, leaving only the Phase-Locked Loop (PLL) still operating. ...

    ... 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 ...
