The System CSR’s are directly addressable memory mapped registers with a base address offset
range of 050h to 2DCh. These registers are addressable by the Host via the Host Bus Interface (HBI).

The System CSR’s can be divided into 9 sub-categories. Each of these sub-categories contains the
System CSR descriptions of the associated registers. The register descriptions are categorized as
follows:
