Configuration of the camera
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 capa-
bilities
• 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.

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.
