Detailed explanation-1: -The zero flag is typically abbreviated Z or ZF or similar in most documentation and assembly languages. Along with a carry flag, a sign flag and an overflow flag, the zero flag is used to check the result of an arithmetic operation, including bitwise logical instructions.
Detailed explanation-2: -Zero flag (ZF)-the zero flag is set(1) when the result of an arithmetic operation is zero. Sign flag (SF)-the sign flag is set(1) when the result of an arithmetic operation has a 1 in the most significant bit (msb).
Detailed explanation-3: -Zero Flag (ZF)-set to 1 when result is zero. For none zero result this flag is set to 0. Sign Flag (SF)-set to 1 when result is negative. When result is positive it is set to 0.
Detailed explanation-4: -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.
