RCR: Rotate Right through Carry:- This instruction rotates the contents bit-wise of the destination operand right by the specified count through carry flag (CF). For each operation, the carry flag is pushed into the MSB of the operand and the LSB is pushed into carry flag. Remaining bits are shifted right by the specified count positions. The PF, SF, ZF are not changed. The operand can be or memory location or a register. Given figure explains this operation.
