WebWhat is JNZ in 8085 microprocessor? Jump if not zero (JNZ) result in 8085 Microprocessor Microprocessor 8085 In 8085 Instruction set, we are having one mnemonic JNZ a16, which stands for “Jump if Not Zero” and “a16” stands for any 16-bit address. This instruction is used to jump to the address a16 as provided in the instruction. WebEach jump operation has three different forms, depending on the size of the operand. A short jump uses an 8-bit signed operand, which is a relative offset from the current instruction. A near jump is similar to a short jump but uses a 16-bit signed operand (in real or protected mode) or a 32-bit signed operand (in 32-bit protected mode only).
