An interrupt in the 8051 microcontroller is a mechanism that temporarily halts the execution of the main program to allow the processor to address an event or condition that requires immediate attention, such as a timer overflow, external signal, or serial communication. The 8051 supports multiple interrupt sources, including external interrupts (INT0 and INT1), timer interrupts (Timer 0 and Timer 1), and a serial communication interrupt. When an interrupt occurs, the microcontroller saves the current program state, jumps to a predefined interrupt service routine (ISR), and upon completion, resumes the original program. This allows for efficient handling of asynchronous events without continuous polling.
What else can I help you with?
Which is the highest priority interrupt for 8051?
The highest priority interrupt in the 8085 is the TRAP interrupt.
What are the five sources of interrupt in 8051 microcontroller?
Intr timer interrupt 0 and 1 external interrupt 0 and 1
What is the function of 02h of int 21h in 8051 processor?
In the 8051 microcontroller, the function of 02h of int 21h is to output a character to the standard output device, typically the serial port. When this interrupt is called, it takes a character from the accumulator (register A) and sends it to the output. This is commonly used for displaying characters on a terminal or for debugging purposes.
Who is first invented 8051 microcontroller or 8051 microprocessor?
Intel
How many instruction in 8051 microcontroller?
how many interrupts in 8051
Why the name 8051 as 8051?
because i said so thats why
What is the difference between microcontroller 8051 and avr atmega16?
avr is high speed cmpar to 8051.in 8051 there are less number of instructions
How much voltage is required to energize the 8051 microcontroller?
The 8051 runs on +5vdc.
Is 8052 family of 8051?
Yes, 8052 family is upgraded version of 8051 family
What are 8051 based systems?
The 8051 is a micro-controller series, basically a computer on a chip. A system based on the 8051 series micro-controller is simply that, a device or series of devices that operate under control of one or more 8051 micro-controllers.
Advantages of at89c51 microcontroller over 8051 microcontroller?
the 8051 microcontrroller is the name doesnt matter easy or not....but the maiin and imp diff between both is at89s51 represents the 8051 chip no....along with the name of company i.e atmel, so all n all both are same thing ...... 89c51 have RISC architecture and contains less no of opcodes which are easy for programming. so iti is preferred than 8051.
Is 8051 a cisc or risc?
8051 is a CISC but having less number of instruction as comared to ARM which is RISC.CISC
