Table 40.
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 42.
The Capability Identifier (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
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
configuration space. If the function does not implement any other capabilities defined 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

Description
DATA: This register is used to report the state dependent data requested
by the D_S field of the PMCSR register. The value of this register is scaled
by the value reported by the DS field of the PMCSR register.
