The following information applies to the CCN-502 registers:
|RW||Read and write.|
|RAZ||Read as zero.|
3.3 Register descriptions describe the configuration registers included in each type of component in a CCN-502 system. The overall configuration register space is determined by the specific product implementation, with inclusion or exclusion of protocol bridges being the main distinction.
Each of the register descriptions is identical for all instances of that component, except for the identification registers. Each component contains all the registers included in its type, but the register space for each component is contained within a 64KB region specific to that component.
The exception to the identical register space across all instances of a specific component is in the
node_id field in the identification registers (*_oly_id) included in all CCN-502 components. This field is different for each component
instance in a CCN-502 system. The value for the node_id
field in the component registers is set to
0x0, although the actual
value for the specific component instances can differ, depending on the configuration and
