DISABLE
Input
When driven high, this input will disable the Voltage Regulator Module
output and the output of the module will float.
Power Good is driven low when the VRM output is not within valid
levels.
Sense is provided for the regulator to correct for voltage drops across
the connector and motherboard powerplane.
This signal indicates to future upgrade processors that the proper
module is installed. This signal must be tied HIGH for this module.
This pin may be used as a +12V supply input, otherwise it should be
left as a no connect (NC)
