ConfigurationROM
The ConfigurationROM is normally used for the OS to identify the device.
The serial number and firmware version of the camera are stored in ConfigurationROM to be used when required. Note
that the setting method for the serial number and firmware version information is of Sony’s unique specification and is
not compatible with cameras of other manufacturers.
The following explanation uses XCD-V60CR as an example.
With the exception of bits 8 to 15 of the 400h offset address field, the length of the entire ConfigROM is made up of
22h Quadlets. Therefore, the ConfigROM from 400h to 48Bh is 140 bytes.
The UnitDirectory offset address is required to be
424h + 000004h × 1 = 424h
For offset address 424h, the length of the UnitDirectory is 3 Quadlets.
UnitSpecID (00A02Dh) conforms to 1394TA standards.
UnitSoftwareVersion (000102h) conforms to IIDC Standards, Version 1.3.
The offset address of UnitDependentInfo is required to be
430h + 000001h × 1 = 434h
