MXVCCIN: MAX VCCIN VID

Offset 35h-34h is the Processor VCCIN maximum VID (Voltage Identification) field and contains the maximum voltage requested via the VID pins. This field, rounded to the next thousandth, is in mV and is reflected in binary coded decimal. Some systems read this offset to determine if all processors support the same default VID setting. Writes to this register have no effect.

Example: A voltage of 1.800 mV maximum core VID would contain 1800h in Offset 35h- 34h.
