Rotate data memory left through carry
The contents of the specified data memory and the carry flag are rotated one
bit left. Bit 7 replaces the carry bit; the original carry flag is rotated into the
bit 0 position.

Rotate left through carry and place result in the accumulator
Data in the specified data memory and the carry flag are rotated one 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.
