Rotate left through carry and place result in the accumulator

Data in the specified data memory and the carry flag are rotated 1 bit left. Bit 7 replaces the

carry bit and the original carry flag is rotated into bit 0 position. The rotated result is stored

in the accumulator but the contents of the data memory remain unchanged.
