Capability ID
This register defines the power management capabilities associated with the PCI bus. The register bits are defined below.
Bit [31:27]: PME Support (R) – Power Management Event Support. This bit field is hardwired to 0x00 to indicate
that the SiI3512 device does not support PME.
Bit [26]: PPM D2 Support (R) – PCI Power Management D2 Support. This bit is hardwired to 1 to indicate
support for the D2 Power Management State.
Bit [25]: PPM D1 Support (R) – PCI Power Management D1 Support. This bit is hardwired to 1 to indicate
support for the D1 Power Management State.
Bit [24:22]: Auxiliary Current (R) – Auxiliary Current. This bit field is hardwired to 0b000.
Bit [21]: Dev Special Init (R) – Device Special Initialization. This bit is hardwired to 1 to indicate that the
SiI3512 controller requires special initialization
Bit [20]: Reserved (R). This bit is reserved and returns zero on a read.
Bit [19]: PME Clock (R) – Power Management Event Clock. This bit is hardwired to 0. The SiI3512 controller
does not support PME.
Bit [18:16]: PPM Rev (R) – PCI Power Management Revision. This bit field is hardwired to 0b010 to indicate
compliance with the PCI Power Management Interface Specification revision 1.1.
Bit [15:08]: Next Item Pointer (R) – PCI Additional Capability Next Item Pointer. This bit field is hardwired to
0x00 to indicate that there are no additional items on the Capabilities List.
Bit [07:00]: Capability ID (R) – PCI Additional Capability ID. This bit field is hardwired to 0x01 to indicate that
this Capabilities List is a PCI Power Management definition.
