With the exception of bits 8 to 15 of the 400h offset
address field, the length of the entire ConfigROM is
made up of 1Fh Quadlets. So the ConfigROM from
400h to 47Fh is 128 bytes.
Offset address 420h and key code 8Dh indicate a
NodeUniqueID Leaf offset, but in 1394a-2000, this
field has been eliminated. To ensure compatibility with

For offset address 434h, the length of the
UnitDirectory is 3 Quadlets. UnitSpecID (00A02Dh)
conforms to 1394TA standards. UnitSoftwareVersion
(000102h) conforms to IIDC Standards, Version 1.30.
