Capabilities Pointer
This register defines the link to a list of new capabilities associated with the PCI bus. The register bits are defined below.
Bit [31:08]: Reserved (R). This bit field is reserved and returns zeros on a read.
Bit [07:00]: Capabilities Pointer (R) – Capabilities Pointer. This bit field defaults to 0x60 to define the address for
the 1
st entry in a list of PCI Power Management capabilities.

Interrupt Pin
Interrupt Line
This register defines the various control functions associated with the PCI bus. The register bits are defined below.
Bit [31:24]: Max Latency (R) – Maximum Latency. This bit field is hardwired to 0x00.
Bit [23:16]: Min Grant (R) – Minimum Grant. This bit field is hardwired to 0x00.
Bit [15:08]: Interrupt Pin (R) – Interrupt Pin Used. This bit field is hardwired to 0x01 to indicate that the SiI3512
controller uses the INTA# interrupt.
Bit [07:00]: Interrupt Line (R/W) – Interrupt Line. This bit field is used by the system to indicate interrupt line
routing information. The SiI3512 device does not use this information.

This register defines the various control functions associated with the PCI bus. The register bits are defined below.
Bit [31:02]: Reserved (R). This bit field is hardwired to 0x00000000.
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 0xC0 and 0xC4 (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 (0x03–0x02), PCI Class Code (0x09–
0x0B), Subsystem Vendor ID (0x2D–0x2C), and Subsystem ID (0x2F–0x2E).
