The following diagram shows some example values for C and the 16-to-4 bit
conversions that they produce.

256-to-8 bit Conversion
When the fourth (leftmost) digit of C is 1, DMPX(077) finds the locations of the
leftmost (highest bit address) or rightmost (lowest bit address) ON bits in one
or two 16-word ranges of source words. The locations of these bits are written
to R beginning with the specified byte. (Set the third digit of C to 0 to find the
leftmost ON bits or 1 to find the rightmost ON bits.)
l =0 (Convert one 16-word range.)
