Processing details
• These instructions search the same data as the 16-bit binary data of (s2) in (n) data starting from (s1), and store the search
result in (d) to (d)+4.
• When the same data exists, five devices starting from (d) store the number of same data, first position, last position,
maximum value position and minimum value position.
• When the same data does not exist, five devices starting from (d) store the number of same data, first position, last position,
maximum value position and minimum value position. In this case, however, 0 is stored in three devices starting from (d)
(which store the number of same data, first position and last position).
