Highest priority interrupt in 8051
Web16 de fev. de 2024 · 8051 has two levels of interrupt priorities: high or low.By assigning priorities, we can control the order in which multiple interrupts will be serviced. Priorities are set by bits in a special function register called IP, which is at the byte address B8H. Web7 de fev. de 2024 · If both interrupts are of the same priority, the interrupt Combination of ip register and polling sequence gives unique priorities to all 5 interrupts in 8051 microcontroller. Additionally, you may have enabled the serial interrupt which is called every time a character is received via the serial port.
