Saving the Microprocessor Registers When a processor is interrupted , it saves at
least the program counter onto the stack so that the processor can return to the
main program after executing the service routine . Some processors save only ...

The 8086 interrupt vectors are defined as follows : Vectors 0 - 4 Vectors 5 - 31
Vectors 32 – 255 For predefined interrupts For Intel ' s future use For user
interrupts Interrupt service routines should be terminated with an IRET ( interrupt
return ) ...
