Ta= 1us minimum (VCCVID > 1V to VID_GOOD high)
Tb= 50ms maximum (VID_GOOD to Vcc valid maximum time)
Tc= T37 (PWRGOOD inactive pulse width)
Td= T36 (PWRGOOD to RESET# de-assertion time)
Note: VID_GOOD is not a processor signal. This signal is routed to the
output enable pin of the voltage regluator control silicon. For more
information on implementation refer to the Intel Mobile Northwood
Processor and Intel 845MP Platform RDDP.

1. This timing diagram is not intended to show specific times. Instead a
general ordering of events with respect to time should be observed.
2.  When VCCVID is less than 1V, VID_GOOD must be low.
3. Vcc must be disabled before VID[4:0] becomes invalid.
4.  VCCVID and Vcc regulator can be disabled simultaneously
