Interrupts

A return-from-interrupt (RTI) instruction is used to signify when the
interrupt software service routine is complete. The RTI instruction
causes the register contents to be recovered from the stack and normal
processing to resume at the next instruction that was to be executed
when the interrupt took place. Figure 4-1 shows the sequence of events
that occurs during interrupt processing. Figure 4-2 shows the stacking
and unstacking order into the RAM that is associated with an interrupt
service routine.
