Device ID
Vendor ID
This register defines the Device ID and Vendor ID associated with the SiI3531A. The register bits are defined below.
Bit [31:16]
: Device ID (R/W) – Device ID. The value in this bit field is one of the following:
the default value of 0x3531 to identify the device as a Silicon Image SiI3531A.
system programmed value; if bit 0 of the Configuration register (48
H
) is set, the Device ID is system
programmable.
Bit [15:00]
: Vendor ID (R) – Vendor ID. This field defaults to 0x1095 to identify the vendor as Silicon Image.

This register defines the various control functions associated with the PCI bus. The register bits are defined below.
Bit 31
: Det Par Err (R/W1C) – Detected Parity Error.
Bit 30
: Sig Sys Err (R/W1C) – Signaled System Error.
Bit 29
: Rcvd M Abort (R/W1C) – Received Master Abort.
Bit 28
: Rcvd T Abort (R/W1C) – Received Target Abort.
Bit 27
: Sig T Abort (R/W1C) – Signaled Target Abort.
Bit 24
: Det M Par Err (R/W1C) – Detected Master Data Parity Error.
Bit 20
: Capabilities List (R) – PCI Capabilities List. This bit is hardwired to 1 to indicate that the SiI3531A
implements Capabilities registers for Power Management, PCI-X, and Message Signaled Interrupt.
Bit [19]
: Interrupt Status (R).
Bit [26:25,23:21,18:11,9,7,5:3]
: Reserved (R). This bit field is reserved and returns zeros on a read.
Bit [10]
: Interrupt Disable (R/W).
Bit 08
: SERR Enable (R/W) – SERR Enable.
Bit 06
: Par Error Resp (R/W) – Parity Error Response Enable.
Bit 02
: Bus Master (R/W) – Bus Master Enable. This bit set enables the SiI3531A to act as PCI bus master, i.e.,
issue Memory Requests.
Bit 01
: Memory Space (R/W) – Memory Space Enable. This bit set enables the SiI3531A to respond to memory
space accesses.
Bit 00
: I/O Space (R/W) – I/O Space Enable. This bit set enables the SiI3531A to respond to I/O space
accesses.
