Rotate Data Memory left through Carry

The contents of the specified Data Memory and the carry flag are rotated left by 1 bit. Bit 7

replaces the Carry bit and the original carry flag is rotated into bit 0.

Rotate Data Memory left through Carry with result in ACC

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

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

the Accumulator and the contents of the Data Memory remain unchanged.
