8051 instruction set

JZ and JNC instructions both jump forward. In line 04, the instruction "JZ NEXT" has opcode of '60' and operand of '03' at the program counter [PC] address Instruction: JZ F7H Opcode: 60H RegBank Bytes: 2 Cycles: 2 Flags Affected: none #0 Program Memory CY AC PO RSIRSO OV ' P Data Memory 0203 I-IuliI-I0202 0201Description: JZ branches to the address indicated by reladdr if the Accumulator contains the value 0. If the value of the Accumulator is non-zero program 8051 Instruction Set: DIV Description: Divides the unsigned value of the Accumulator by the unsigned value of the "B" register. The resulting quotient is Instruction : JZ F7H Opcode : 60H Reg . Bank # 0 Bytes : 2 Cycles : 2 Flags Affected : none CY AC FO RS1RSO OV PSWI 00 Р Data Memory DOH 31 30 2F Reg . The JNZ instruction transfers control to the specified address if the value in the accumulator is not 0. If the accumulator has a value of 0, the next In the 8051, the loop action is performed by the instruction “DJNZ reg, label”. In this instruction, the register is decremented; if it is not zero, it jumps
