Type
| Function |
|
Description
| Performs a bitwise left shift operation on the WORD operand connected to the input IN. N specifies the number of bits to be shifted. |
|
Notes
|
- The empty bit positions resulting from the shift operation are filled with zeros.
- When shifting with N < 0, the function delivers the output value 0 because the parameter N is always considered as an unsigned integer value.
- The function does not support execution control with EN/ENO.
