Function - Rotate bits of a register to the left.
IN : SINT
8 bit register
NBR : SINT Number of rotations (each rotation is 1 bit)
Q : SINT Rotated register
In LD language, the input rung (EN) enables the operation, and the output rung keeps the state of the input rung. In IL language, the first input must be loaded before the function call. The second input is the operand of the function.
Q := ROLb (IN, NBR);
(* The rotation is executed only if EN is
(* ENO has the same value as EN *)
