Product data sheet
8.2.3.1 Cap_ID register
8.2.3.2 Next_Item_Ptr register
8.2.3 Power management registers
established by BIOS initializing this register to a system-specific value. The system
software uses the information in this register when enabling devices and ports for remote
wake-up.
Table 29:

Table 30:
The Capability Identifier (Cap_ID) register when read by the system software as 01h
indicates that the data structure currently being pointed to is the PCI Power Management
data structure. Each function of a PCI device may have only one item in its capability list
with Cap_ID set to 01h. The bit description of the register is given in
Table 31:
Address: Value read from address 34h + 0h
Legend: * reset value
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 power management is the last item in
the list, then this register must be set to 00h. See

Data
Description
Next Item Pointer: This field provides an offset into
the function’s PCI configuration space pointing to the
location of the next item in the function’s capability list.
If there are no additional items in the Capabilities List,
this register is set to 00h.
