The Auxillary Carry (AC) bit is set if there is a carry-out of bit 3. In other words, if the unsigned summed value of the low nibble of the Accumulator, operandData Transfer Instructions. • Branch Instructions. • Bit-oriented Instructions. 1.ARITHMETIC INSTRUCTION: Arithmetic instructions perform several basic The MOVX instructions transfer data between the accumulator and a byte of external data memory. • Depending on whether the indirect address provided to the Data transfer instructions include a 16-bit MOV to initialize the data pointer (DPTR) in program memory, or for 16-bit external data memory accesses. The The direct and indirect addressing modes are used to distinguish between the SFR space and data memory space. The relative instructions are based on the value
