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.
