Varying The Word Order - Texas Instruments TMS320C54x User Manual

Figure 10–6. Varying the Word Order
Note: When the –order Option Applies
-
This option applies only when you use a memory width with a value less
than 16. Otherwise, –order is ignored.
-
This option does not affect the way memory words are split into output
files. Think of the files as a set: the set contains a least significant file and
a most significant file, but there is no ordering over the set. When you list
filenames for a set of files, you always list the least significant first, regard-
less of the –order option.
Figure 10–6 demonstrates how –order affects the conversion process. This
figure, and the previous figure, Figure 10–4, explain the condition of the data
in the hex conversion utility output files.
