WebNov 29, 2024 · 1 Answer. It can be tricky to interpret condition codes in the absence of a CMP instruction, because the mnemonics were written to make interpretation easy when there's a CMP. But in this example, it's not so bad: remember that CMP is just SUBS … WebBNE only supports the Relative addressing mode, as shown in the table at right.In the assembler formats listed, nn is a one-byte (8-bit) relative address. The relative address is treated as a signed byte; that is, it shifts program execution to a location within a number of bytes ranging from -128 to 127, relative to the address of the instruction following the …
