The RR instruction rotates the eight bits in the accumulator right one bit position. Bit 0 of the accumulator is rotated into bit 7, bit 7 into bit 6, and so on. No flags are affected by this instruction. 8051 Instruction Set: RR. Operation: RR; Function: Rotate not a documented instruction. The 8051 supports 255 instructions and OpCode 0xA5 is the single OpCode 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. 8051 Microcontroller Instruction Set 1-5 Atmel 8051 Microcontrollers Hardware Manual 0509C–8051–07/06 RR A Rotate Accumulator Right 112 RRC A Rotate Accumulator RRC - Rotate Accumulator Right through Carry - RRC 8051 / 8052 Microcontroller Instruction Set - Instructions Set of 8051 / 8052 - 8052 Microcontroller Tutorial - Instruction Set of 8051 / 8052 - ACALL, ADD, ADDC, AJMP, ANL, CJNE, CLR, CPL, DA, DEC, DIV, DJNZ, INC, JB, JBC, JC, JMP, JNB, JNC, JNZ, JZ, LCALL, LJMP, MOV, MOVC, MOVX, MUL, NOP, ORL RR - Rotate Accumulator Right - RRC 8051 / 8052 Microcontroller Instruction Set - Instructions Set of 8051 / 8052 - 8052 Microcontroller Tutorial - Instruction Set of 8051 / 8052 - ACALL, ADD, ADDC, AJMP, ANL, CJNE, CLR, CPL, DA, DEC, DIV, DJNZ, INC, JB, JBC, JC, JMP, JNB, JNC, JNZ, JZ, LCALL, LJMP, MOV, MOVC, MOVX, MUL, NOP, ORL, POP, PUSH #data 8-bit constant included in instruction.
