Explanation of function and operation
1) This function shifts word [unsigned]/bit string [16-bit]/double word [unsigned]/bit string [32-bit] data stored
in a device specified in
using the data type of data stored in a device specified in
d
Data is shifted leftward by "n" bits specified in
Example: When word [unsigned]/bit string [16-bit] data is stored in a device specified in
s
bit string [16-bit] data)
270FH 0
0
F00H
2) "n" bits from the least significant bit become "0".
