How carry and zero flag bits are modified after CMP instruction is executed?
The instruction format is CMP R1, R2. How will the carry and zero flags we be modified after above instruction is executed? Case 1: R1< R2 Carry Flag = 1 Zero Flag = 0 R1= R2 Carry Flag = 0 Zero Flag = 1 R1> R2 ... 0 Zero Flag = 1 R1> R2 Carry Flag = 1 Zero Flag = 0 Which one of the above two cases is correct?
