Webprogramming. Interrupts may be generated by internal chip operation or provided by external sources. Any interrupt can cause the 8051 to perform a hardware call to an interrupt-handling subroutine that is located at a predetermined absolute address in program memory. The 8051 has five interrupts of which three are internally generated … WebInterrupt Handling Mechanism. 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 over while executing the firmware in the program memory. This process is indicated in the figure below. hitman absolution silent assassin guide
