Note: It is recommended that stack pointer be return to rate before INTATRAP (Increment
executed. Thus, the next interrupt can be accepted immediately after the interrupt
return instruction is executed.
Note: When the interrupt processing time is longer than the interrupt request generation
Interrupt requests are sampled during the final cycle of the instruction being
Example 1: Returning from address trap interrupt (INTATRAP) service program.
