Description
Set to enable Vital Product Data.
VPD data is stored in the 93C46 from within offset 40h-7Fh.
Power Management Enable.
Writable only when the 93C46CR register EEM1:0 = [1:1].
Let A denote the New_Cap bit (bit 4 of the Status Register) in the PCI
Configuration space offset 06H.
Let B denote the Cap_Ptr register in the PCI Configuration space offset 34H.
Let C denote the Cap_ID (power management) register in the PCI
Configuration space offset 50H.
Let D denote the power management registers in the PCI Configuration space
offset from 52H to 57H.
Let E denote the Next_Ptr (power management) register in the PCI
Configuration space offset 51H.
