RAR  Rotate Accumulator Right Through Carry Instruction

This instruction rotates the contents  of the  accumulator  towards right by  one bit. The D7  bit moves to D6 position D6  bit moves to D5 position  and so on.  Finally  D0  bit moves  to the carry  flag  position in flag  register and carry  but is  copied  to D7  position the instruction  format is

RAR

Flag : Only CY  flag is  modified according to D0 bit of the  accumulator.
