Bit [01]: BA5 Ind Acc Ena (R/W) – BA5 Indirect Access Enable. This bit is set to enable indirect access to
BA5 address space using Configuration Space registers C0H and C4H (BA5 Indirect Address and BA5
Indirect Access).
Bit [00]: PCI Hdr Wr Ena (R/W) – PCI Configuration Header Write Enable. This bit is set to enable write
access to the following registers in the PCI Configuration Header: Device ID (03-02H), PCI Class Code (09-
0BH), Subsystem Vendor ID (2D-2CH), and Subsystem ID (2F-2EH).

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 00
H to
indicate that the SiI3114 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 000
B.
Bit [21]: Dev Special Init (R) – Device Special Initialization. This bit is hardwired to 1 to indicate that the
SiI3114 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 SiI3114 does
not support PME.
Bit [18:16]: PPM Rev (R) – PCI Power Management Revision. This bit field is hardwired to 010
B 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
00H 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 01
H to indicate that
this Capabilities List is a PCI Power Management definition.
