Device ID
Vendor ID
This register defines the Device ID and Vendor ID associated with the SiI 0680A. The register bits are defined below.
Bit [31:16]
: Device ID (R/W) – Device ID. This value in this bit field is determined by any one of three options:
1) This field defaults to 0x0680 to identify the device as a Silicon Image SiI 0680A.
2) loaded from an external memory device : If an external memory device – FLASH or EEPROM – is
present with the correct signature, the PCI Class Code is loaded from that device after reset. The
correct signature for an EEPROM device is the data pattern 55AA
H
at addresses [03
H
:02
H
] and 55AA
H
at addresses [01
H
:00
H
]. The correct signature for a FLASH device is the data pattern AA55
H
at
addresses [7FFFF
H
:7FFFE
H
] and 55
H
at address 7FFFC
H
. See chapter 8 for details.
3) system programmable : If Bit 0 of the Configuration register (40
H
) is set, to enables writes, the three
bytes are system programmable.
Bit [15:00]
: Vendor ID (R) – Vendor ID. This field defaults to 0x1095 to identify the vendor as Silicon
Image/CMD Technology.

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. This bit set indicates that the SiI 0680A detected a parity
error on the PCI bus-address or data parity error-while responding as a PCI target.
Bit 30
: Sig. Sys Err (R/W1C) – Signaled System Error. This bit set indicates that the SiI 0680A signaled SERR
on the PCI bus.
Bit 29
: Rcvd M Abort (R/W1C) – Received Master Abort. This bit set indicates that the SiI 0680A terminated a
PCI bus operation with a Master Abort.
Bit 28
: Rcvd T Abort (R/W1C) – Received Target Abort. This bit set indicates that the SiI 0680A received a
Target Abort termination.
Bit 27
: Sig. T Abort (R/W1C) – Signaled Target Abort. This bit set indicates that the SiI 0680A terminated a PCI
bus operation with a Target Abort.
Bit [26:25]
: Devsel Timing (R) – Device Select Timing. This bit field indicates the DEVSEL timing supported by
the SiI 0680A. The hardwired value is 01
B
for Medium decode timing.
Bit 24
: Det M Data Par Err (R/W1C) – Detected Master Data Parity Error. This bit set indicates that the SiI
0680A, as bus master, detected a parity error on the PCI bus. The parity error may be either reported by the
target device via PERR# on a write operation or by the SiI 0680A on a read operation.
Bit 23
: Fast B-to-B Capable (R) – Fast Back-to-Back Capable. This bit is hardwired to 1 to indicate that the SiI
0680A is Fast Back-to-Back capable as a PCI target.
Bit 22
: Reserved (R).
