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

The configuration ROM is divided into
•
Bus info block: providing critical information about bus-related capabil-

•
Root directory: specifying the rest of the content and organization,
such as:
– Node unique ID leaf
– Unit directory
– Unit dependant info
such as:
– Node unique ID leaf
– Unit directory
– Unit dependant info
The base address of the camera control register is calculated as follows based
on the camera-specific base address:
on the camera-specific base address:
The entry with key 8D in the root directory (420h in this case) provides the
offset for the Node unique ID leaf.

To compute the effective start address of the node unique ID leaf:
