"In the microcontroller we’re using (PIC16F877A), the interrupts are non-vectored in memory. So there is a common interrupt vector @ the address 0004h, which is always skipped overwhile executing the firmware in the program memory. This process is indicated in the figure below As we previously mentioned, there is … Visa mer Interrupts are basically internal/external signals that suspend the main routine being done/executed. While reading this article, your main … Visa mer Well, an embedded computer (e.g. MCU) is able to respond to any event in two different schemes. The first one is called Polling, which is … Visa mer The interrupt circuitry is the digital logic circuit that drives the interruption systems within the microcontroller.
