WebHardware interrupt vector. The interrupt vector is a location in memory that you program with the address of your interrupt service routine (ISR). Whenever an unmasked interrupt occurs program execution starts from the address contained in the interrupt vector. For PIC micros the hardware interrupt vector address is usually 0004.
