Rotate data memory left through carry
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
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.

Rotate right and place result in the accumulator
Data in the specified data memory is rotated 1 bit right with bit 0 rotated into bit 7, leaving
the rotated result in the accumulator. The contents of the data memory remain unchanged.

Rotate data memory right through carry
The contents of the specified data memory and the carry flag are together rotated 1 bit
right. Bit 0 replaces the carry bit; the original carry flag is rotated into the bit 7 position.
