Data path operations for the various supported endianess and word swap configurations are illustrated
in
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]).
