The RRC instruction rotates the eight bits in the accumulator and the one bit in the carry flag right one bit position. Bit 0 of the accumulator is rotated into the carry flag while the original value of the carry flag is rotated in to bit 7 of the accumulator. Bit 7 of the accumulator is rotated into bit 6, bit 6 into bit 5, and so on. No other flags are affected by this instruction.
