RLC [m]
Rotate data memory left through carry
Description
The contents of the specified data memory and the carry flag are rotated 1 bit left. Bit 7 re-
places the carry bit; the original carry flag is rotated into the bit 0 position.

Rotate left through carry and place result in the accumulator
Description
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.
