Explanation:
Detailed explanation-1: -The microcontroller has 14 interrupt sources. From the diagram below you can see all the sources of the interrupts, when xxIF is an interrupt flag and xxIE is an Interrupt Enable bit.
Detailed explanation-2: -An external interrupt happens due to an interference by some external hardware on specific pins of the microcontroller. PIC18F4550 can handle up to three external interrupts.
Detailed explanation-3: -Interrupts are the signals which alter the flow of an executing program by causing the microcontroller jumps to the Interrupt Service Routine to serve to interrupt. These interrupts are given to the microcontroller unit through the external pins of the microcontroller.
