57
The Data Register is located in 47h of the PCI Configuration Space. (See 2.3 PCI Power
Management Interface for further details.)
Serial ROM Address(2Dh) : PMC Data 4
Serial ROM Address(2Dh) is used to specify the reading value from Data Register in case Data
Select bits(PMCSE[12:9]) of PMCSR equal to 4h. In other words, it indicates the D0 State Power
Dissipated.
The Data Register is located in 47h of the PCI Configuration Space. (See 2.3 PCI Power
Management Interface for further details.)
Serial ROM Address(2Eh) : PMC Data 7
Serial ROM Address(2Eh) is used to specify the reading value from Data Register in case Data
Select bits(PMCSE[12:9]) of PMCSR equal to 7h. In other words, it indicates the D3 State Power
Dissipated.
The Data Register is located in 47h of the PCI Configuration Dpace. (See 2.3 PCI Power
Management Interface for further details.)
Serial ROM Address (2Fh) : NEXT PTR1
Serial ROM Address(2Fh) represents Next Item Pointer of VPD Capability List.
This is used to use the PCI Power Management Interface Capability or the CompactPCI Hot
Swap Capability other than the VPD Capability.
If 40h is stored, the PCI Power Management Capability is enabled, and if 50h is stored, the
CompactPCI Hot Swap Capability is enabled.
If 00h is stored, no more Capability is enabled.
Note : The Next Item Pointer in the CompactPCI Hot Swap Capability List is fixed to 00h. It is
because the CompactPCI Hot Swap Capability is the last Capability provided by SB4002A, and
that the user doesn't need to handle it unlike the Next Item Pointers of other Capabilities.
Serial ROM Address(30h~) : Reserved
Serial ROM Address 30h~ is reserved. You have to store the 00h data.
