SHL
FunctionA function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Shift bits of a register to the left.
Inputs
IN : ANY register
NBS : ANY Number of shifts (each shift is 1 bit)
Outputs
Q : ANY Shifted register

Remarks
Arguments can be signed or unsigned integers from 8 to 32 bits.
In FFLD language, the input rung (EN) enables the operation, and the output rung keeps the state of the input rung. In IL"Instruction list" This is a low-level language and resembles assembly language, the first input must be loaded before the function call. The second input is the operand of the function.
ST Language
Q := SHL (IN, NBS);

(* The shift is executed only if EN is TRUE *)
(* ENO has the same value as EN *)
