These instructions execute on the basis of the content of accumulator. When these instructions execute, the content of accumulator will shift by 1 bit either left or right as per the instruction.
1. RLC no operand
Instruction word size ⇒ 1 Byte
Operation ⇒ When this instruction will execute the content of accumulator will shift (or rotate) left by 1 bit without carry flag.
Addressing Mode ⇒ Implicit Addressing Mode
2. RAL no operand
Instruction word size ⇒ 1 Byte
Operation ⇒ When this instruction will execute the content of accumulator will shift (or rotate) left by 1 bit with carry flag.
Addressing Mode ⇒ Implicit Addressing Mode
3. RRC no operand
Instruction word size ⇒ 1 Byte
Operation ⇒ When this instruction will execute the content of accumulator will shift (or rotate) right by 1 bit without carry flag.
Addressing Mode ⇒ Implicit Addressing Mode
4. RAR no operand
Instruction word size ⇒ 1 Byte
Operation ⇒ When this instruction will execute the content of accumulator will shift (or rotate) right by 1 bit with carry flag.
Addressing Mode ⇒ Implicit Addressing Mode
Note: Rotational instruction affect only one flag i.e. carry flag.
