Configuration ROM
The information in the Configuration ROM is needed to identify the node, its
capabilities and which drivers are required.
The base address for the configuration ROM for all registers is
FFFF F0000000h.
The ConfigRom is divided into the
• Bus info block: providing critical information about the bus-related
capabilities
• Root directory: specifying the rest of the content and organization,
such as:
– Node unique ID leaf
– Unit directory and
– Unit dependant info
The base address of the camera control register is calculated as follows based
on the camera-specific base address:
Note

If you want to use the Direct access program to read or write
to a register, enter the following value in the Address field:
F0F00000h + Offset
Note

The following assignments are only an example.
Because the key code can describe the roll of a register, the
order of some registers is not mandatory.
Bus info block
Offset 0-7 8-15 16-23 24-31
400h 04 29 C3 17
404h 31 33 39 34 …. ASCII for 1394
408h 20 00 A2 02 …. Bus capabilities
40Ch 00 0A 47 01 …. Node_Vendor_Id , Chip_id_hi
410h Serial number …. Chip_id_lo
Root directory
414h 00 04 CRC According to IEEE 1212, the root directory
length may vary. The keys (e.g. 8D) point
to the offset factors rather than the offset
(e.g.420h) itself.
418h 03 00 0A 47
41Ch 0C 00 83 C0
420h 8D 00 00 02
424h D1 00 00 04
