Function
The lower four bits of each of n 16-bit data entries from head address S are combined. The 16-bit data after
combination is stored in D.
n ranges from 1 to 4. The instruction is not executed when n = 0. When n is in the range 1 to 3, the
remaining higher bits are lled with 0s.

An operation error occurs in the following conditions. The error ag M8067 is set to ON to identify this error
and the error code is stored in D8067.
1. Error K6705 is returned when the start number S is out of range.
2. Error K6706 is returned when the value of n is out of range.
