WebBRNE: BRNE refers to the "Branch if not Equal". It is a type of conditional relative branch. If zero flag (Z) is cleared, this instruction will test the Z and branches relative to PC (Program counter). Suppose there are two registers, D (destination register) and S (source register), containing signed or unsigned binary numbers. WebThe mnemonic BRNE stands for 2. True or false.
