The System CSR’s are directly addressable memory mapped registers with a base address offset
range of 050h to 2DCh. These registers are accessed through the I
MIIM/SMI serial interface. For more information on the various LAN9313/LAN9313i modes and their
corresponding address configurations, see
Table 13.1
reset to their default value on the assertion of a chip-level reset.
The System CSR’s can be divided into 8 sub-categories. Each of these sub-categories contains the
System CSR descriptions of the associated registers. The register descriptions are categorized as
follows:
