WebOct 28, 2024 · Software Interrupts in 8051. Software interrupts are generated by the program itself inside the controller. Generating software interrupt in the 8051 microcontrollers is tricky. When an external interrupt is received at INT0 pin TCON.0 bit (IT0) would be set automatically and the processor generates an interrupt. WebA hardware interrupt is a signal that stops the current program forcing it to execute another program immediately. The interrupt does this without waiting for the current program to finish. It is unconditional and immediate which is why it is called an interrupt - it interrupts the current action of the processor.
