Splet26. jul. 2024 · There are 5 different ways to execute this instruction and hence we say, we have got 5 addressing modes for 8051. They are 1) Immediate addressing mode 2) Direct addressing mode 3) Register direct addressing mode 4) Register indirect addressing mode 5) Indexed addressing mode. Immediate Addressing Mode Let’s begin with an example. … Splet24. apr. 2024 · MOVX Instruction. The 8051 microcontroller in most cases has an on-chip 4K flash memory, but due to its 16-bit address bus, it can access 64k memory locations. Due to this reason, the 8051 can be interfaced with external memory using ports 0 and 2. To access data in this external memory, the MOVX instruction is used.
