Device ID
Vendor ID
This register defines the Device ID and Vendor ID associated with the
SiI
3114. 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 0x3114 to identify the device as a Silicon Image
SiI
3114.
2) Loaded from an external memory device: If an external memory device — flash or EEPROM — is
present with the correct signature, the Device ID is loaded from that device after reset. See “Auto-
Initialization” section on page 22 for more information.
3) System programmable : If Bit 0 of the Configuration register (40
H
) is set, the bytes are system
programmable.
Bit [15:00]
: Vendor ID (R) – Vendor ID. This field defaults to 0x1095 to identify the vendor as Silicon
Image.
