9.2 Vectored Interrupt
When a branch to an interrupt handling routine occurs, the vector table address corresponding to the interrupt
source is used as the branch address.
Interrupt handling by the CPU consists of the following operations:
When a branch occurs
When control is returned: Pop the CPU status (PC and PSW contents) from the stack.
: Push the CPU status (PC and PSW contents) to the stack.
To return control from the handling routine to the main routine, use the RETI instruction. The branch destination
addresses must be within the range of 0 to FFFFH.
