Outline of operation
● This instruction counts the number of ONs for [n] bits from the device specified by [S1].
● During the counting operation, a data area that is equal to n/16 words from the device
specified in [S2] is used.
● The count result is stored in the area of [n]*2 words starting with [D].
● The working area with the starting address specified by [S2] needs the following number of
words:
