Shift Left (SL)

Use this instruction to shift all the bits in the variable to the left and load either a 1 or 0

into the least significant bit position for each falseĆtrue transition of the enable input.
When EN transitions from false to true, the bits of In are shifted one position to the left.

The most significant bit is moved to OUT, and the value of BIT is shifted into the least

significant bit position of In.
