In this article, we will delve into the various addressing modes in 8051 microcontroller, exploring their functionalities and benefits in the programming. One of the key features of 8051 microcontroller that contribute to its versatility is the wide range of addressing modes it supports. Addressing modes determine how the operands for an instruction are accessed, […]
The 8051 has two types of memory and these are Program Memory and Data Memory. Program Memory (ROM) is used to permanently save the program being executed, while Data Memory (RAM) is used for temporarily storing data and intermediate results created and used during the operation of the microcontroller. Let’s have a brief detail of
The 8051 microcontroller is one of the most popular and widely used microcontrollers in the world. It was first introduced by Intel in 1980 and has since been used in a wide range of applications, including industrial control systems, automotive systems, consumer electronics, and more. In this article, we will explore the features of the
Various assembler directives in 8051 microcontrollers are used during assembly language programming. Unlike instructions being compiled and written to chip program memory, directives are commands of assembly language itself and have no influence on the operation of the microcontroller. Some of them are obligatory part of every program while some are used only to facilitate
