microcontroller. The best way to address the operand is nothing other than the addressing mode. II.DIFFERENT ADDRESSING MODES. The 8051 instructions use . machine instruction. Addressing modes are an aspect of the instruction set architecture in most central processing unit (CPU) designs. An addressing mode.
The 8051 instructions use eight addressing modes. These are: 1. Register 2. Direct 2.1) External Direct 3. Indirect 3.1) External Indirect 4. Immediate 5. Relative 6. Absolute 7. Long 8. Indexed Each of these addressing modes provides important flexibility. 1. 8051 Microcontroller: Addressing Modes. 1) Register Addressing

ADDRESSING MODES OF 8051/8031 MICROCONTROLLER. • Every instruction of a program has to operate on a data. • The method of specifying the data to be operated by the instruction is called addressing. • The 8031 has the following types of addressing. 1. Immediate Addressing. 2. Direct Addressing. 3. Register

main aspects: hardware architecture, applications, and instruction set features Instruction set: – Microprocessor instruction sets are processing intensive. • Their instructions operate on nibbles, bytes, words, or even double words. • Addressing modes . There are eight addressing modes available in the 8051: – Register.
