When 00000 is ON, the following diagram encodes IR words 200 and 201 to the
first two digits of HR 10 and then encodes LR 10 and 11 to the last two digits of
HR 10. Although the status of each source word bit is not shown, it is assumed
that the bit with status 1 (ON) shown is the highest bit that is ON in the word.
