Circular Rotate Bits Left on Transition (RL)

Use this instruction to rotate all the bits within a variable a specified number of bit

positions to the left on a falseĆtrue transition. The bits are rotated left from the most

significant bit positions and into the least significant bit positions.
When EN transitions from false to true, the following occurs:
D the number of the most significant bits of In specified in N are moved from In
D the remaining bits shift left
D the bits rotated from the most significant bits of In are filled into the least significant

bit positions of In

The specified number of bits are rotated left only when EN transitions from false to true.
