djnz instruction in 8051
write an assembly language program to transfer data from one memory location to another location

The MOVX instruction is used when external memory is to be interfaced. This performs data transfer only between external memory and accumulator. Instruction types. ➢ Arithmetic operations. ➢ Logical operations. ➢ Data transfer instructions. ➢ Boolean variable instructions. ➢ Program branching Since only 11 bits of the Program Counter are affected by AJMP, jumps may only be made to code located within the same 2k block as the first byte that followsInstruction using #. ➢ The program counter is automatically incremented to point to the byte(s) following the opcode byte in the program memory. MOV a, #n. All the instructions of microcontroller 8051 may be classified based on the functional aspect are given below. • Data transfer group. • Arithmetic group.
