The device will save the program counter value to the stack (bookmark the page), know which interrupt is triggered (identify the caller) and execute the interrupt routine (talk to the caller). When the interrupt routine is finished, the device will read the program counter from the stack so that it can go back to where it stopped on the main. The program counter acts as a pointer to the instructions stored in the program memory. EEPROM: It consists of 256 bytes of memory space. It is a permanent memory like ROM, but its contents can be erased and changed during the operation of the microcontroller. The contents into EEPROM can be read from or written to, using special function.
