JZ - Jump if Accumulator Zero; LCALL - Long Call; LJMP - Long Jump; MOV - Move Memory; MOVC - Move Code Memory; MOVX - Move Extended Memory; MUL - Multiply Accumulator by B; NOP - No Operation; ORL - Bitwise OR; POP - Pop Value From Stack; PUSH - Push Val,The JBC instruction branches to the address specified in the second operand if the value of the bit specified in the first operand is 1.Otherwise, execution continues with the next instruction. If the bit specified in the first operand is set, it is clear,The JZ instruction transfers control to the specified address if the value in the accumulator is 0. Otherwise, the next instruction is executed. Neither the accumulator nor any flags are modified by this instruction. See Also: JNZ JZ offset C AC F0 RS1 RS,The ORL instruction performs a bitwise logical OR operation on the specified operands, the result of which is stored in the destination operand. Note When this instruction is used to modify an output port, the value used as the port data will be read from,In 8051 , JZ or JNZ instruction may be used immediately after loading the accumulator by an immediate data. However, this is not possible in case of 8085 as these instructions are dependent upon the condition of Z flag of 8085, which is not affected by an,JZ rel. 若A=0跳至rel. 24. JNZ rel. 若A不等於0跳至rel. 24.
