8.2 Vectored Interrupt
Execution branches to a servicing routine by using the memory contents of a vector table address corresponding
to the interrupt source as the address of the branch destination.
So that the CPU performs interrupt servicing, the following operations are performed:
On branching: Saves the status of the CPU (contents of PC and PSW) to stack
On returning: Restores the status of the CPU (contents of PC and PSW) from stack
To return to the main routine from an interrupt service routine, the RETI instruction is used.
The branch destination address is in a range of 0 to FFFFH.
