7 VccVID Voltage
7.1 VccVID Voltage (PROPOSED)
This section is included for reference: Intel does not recommend integration with the processor
Vcc PWM controller.
The VccVID output powers the processor VID outputs. This rail must come up and assert an
active-high VID_PWRGD output according to the timing specified in Figure 7 and Table 9. There
is no enable function for the VccVID regulator controller
