Base Address Register 1
0 0000 0000 0100
This register defines the addressing of the Port Registers and LRAM within the SiI3531A. The register bits are defined below.
Bit [63:13]: Base Address Register 1 (R/W). This register defines the base address for the 16Kbyte Memory
Space containing the Port Registers.
Bit [12:00]: (R). This bit field is hardwired to 0004H to indicate a 64-bit base address.

Subsystem ID
Subsystem Vendor ID
This register defines the Subsystem ID fields associated with the PCI bus. The register bits are defined below.
Bit [31:16]: Subsystem ID (R/W) – Subsystem ID.
The value in this bit field is one of the following:
the default value of 0x3531
system programmed value; if bit 0 of the Configuration register (48H) is set the Subsystem ID is system
programmable.
Bit [15:00]: Subsystem Vendor ID (R/W) – Subsystem Vendor ID.
The value in this bit field is one of the following:
the default value of 0x1095
system programmed value; if bit 0 of the Configuration register (48H) is set the Subsystem Vendor ID is
system programmable.
