Explanation of function and operation
1. 16-bit operation (UNI/UNIP)
1) The low-order 4 bits of "n" 16-bit data starting from are combined, and stored in as shown below.
2) Specify a number 1 to 4 in "n".
In the case of "n = 0", UNI instruction is not executed.
3) In the case of "1 ≤ n ≤ 3", the high-order {4 × (4-n)} bits of are set to "0".
For example, when "n" is "3", the low-order 4 bits of to +2 are stored in b0 to b11 of , and the
high-order 4 bits of are set to "0".
Operand type Description Data type
Head device number storing data to be combined
16-bit binary
Device number storing combined data
n Number of data to be combined (0 to 4, When "n" is "0", UNI instruction is not executed.)
