What are the classification of instruction set in 8051?
The complete 8051 Instruction Set or all 8051 instructions are broadly classify in to four groups data moving, logical, arithmetic and branching.
How many branch instructions are in the instruction set of 8051 microcontroller?
In 8051 Microcontroller there is 17 different instructions under the Logical Group. In total there are 46 opcodes.
How many zero byte instructions are there in the instruction set of 8051?
All commands are known as INSTRUCTION SET. All microcontrollers compatibile with the 8051 have in total of 255 instructions, i.e. 255 different words available for program writing.
What is instruction set in microcontroller?
The instruction set of microcontroller is a collection of instructions that the microcontroller is designed to execute.
What is instruction and instruction set?
An instruction set is a group of commands for a CPU in machine language. The term can refer to all possible instructions for a CPU or a subset of instructions to enhance its performance in certain situations. Some instructions are simple read, write and move commands that direct data to different hardware.
What is instruction set microcontroller?
What is meant by instruction set?
What is branch instruction 8051?
Branch Instructions. There are two kinds of branch instructions: Unconditional jump instructions: upon their execution a jump to a new location from where the program continues execution is executed. Conditional jump instructions: a jump to a new program location is executed only if a specified condition is met.

What are the features of 8051?
Following are the main features of Micro controller 8051 which makes it most efficient Microcontroller chip: It Includes Boolean Processing Engine. It gives us many functions in a single chip. It have 8 bit Data bus. It have 8 bit Stack Pointer. It have 16 bit Program Counter. It have 16 bit address bus which can access almost 65,536 memory locations. Data memory or RAM of 128 bytes. Program Memory or ROM of 4 KB. Bi-Directional I/O port of 4 bytes.
Why is the 8051 microcontroller called that?
In 1981, Intel introduced an 8-bit microcontroller called the 8051. It was referred as system on a chip because it had 128 bytes of RAM, 4K byte of on-chip ROM, two timers, one serial port, and 4 ports (8-bit wide), all on a single chip.
What IC is used for 8051?
The IC L293D is used for interfacing 8051 with DC motor as shown in the block diagram. The two input buttons can be used to control the output PWM generated by the microcontroller. This output signal is then fed to DC motor through motor driver.
What is the Register use in 8051?
8051 Microcontroller Registers TCON (Timer Control register) TCON is an 8-bit register. TH0/TL0 & TH1/TL1. TMOD (Timer Mode register) There are 4 modes in which timer can be loaded. SCON (Serial Control) It’s an 8 bit register, Used for serial data communication. SBUFF (Serial Buffer) This register is used when we are transmitting or receiving data serially.
