6.2 INTEN INTERRUPT ENABLE REGISTER
INTEN is the interrupt request control register including one internal interrupts, one external interrupts enable control
bits. One of the register to be set “1” is to enable the interrupt request function. Once of the interrupt occur, the stack is
incremented and program jump to ORG 8 to execute interrupt service routines. The program exits the interrupt service
routine when the returning interrupt service routine instruction (RETI) is executed.
