Timing After Interrupt
The interrupt processing routine begins with the
machine cycle following the completion of the
instruction that is currently in execution.
Figure 52 shows a timing chart after an interrupt
occurs, and Figure 53 shows the time up to execution
of the interrupt processing routine.
