Figure 3.2 LAN9211 Host Data Path Diagram
Data path operations for the various supported endianess and word swap configurations are illustrated
in
Figure
3.3.
Table 3.8, "Endian Ordering Logic Operation"
illustrates the byte ordering applied by the
endian logic for each type of host access. This figure and table assume an internal byte ordering of 3-
2-1-0, where ‘3’ is the most significant byte (data[31:24]) and ‘0’ is the least significant byte (data[7:0]).
