8.2.3.6
Data register
The Data register is an optional, 1-byte register that provides a mechanism for the
function to report state dependent operating data, such as power consumed or heat
dissipated. Table 41 shows the bit description of the register.
8.2.4 VPD register
8.2.4.1
VPD_Cap_ID register
The Capability Identier (Cap_ID) register when read by the system software as 03h
indicates that the data structure currently being pointed to is the VPD_Data structure. The
bit description of the register is given in Table 43.
8.2.4.2
VPD_Next_Item_Ptr register
The Next Item Pointer (Next_Item_Ptr) register describes the location of the next item in
the function’s capability list. The value given is an offset into the function’s PCI
conguration space. If the function does not implement any other capabilities dened by
the PCI-SIG for inclusion in the capabilities list, or if the power management is the last
item in the list, then this register must be set to 00h. See Table 44.
