FUNCTIONAL DESCRIPTION SUPPLEMENT
Timing After Interrupt
The interrupt processing routine begins with the machine cycle fol-
lowing the completion of the instruction that is currently in execu-
tion.
Figure 32 shows a timing chart after an interrupt occurs, and Fig-
ure 33 shows the time up to execution of the interrupt processing
routine.
