Outline of operation
● This instruction multiplies the BCD data for [S1] and [S2] by the operation unit [i].
● The calculation result is stored in the address starting with [D].
[S1] × [S2] → ([D], [D]+1)
● The unit size of the operation result output in [D] is twice as large as the operation unit.
