When the process is returned after an interrupt service ______ should ...
Explanation:
When an interrupt occurs, the processor saves the current context of the process and jumps to the interrupt service routine. After the ISR is completed, the processor returns to the interrupted process. At this point, the following actions should take place:
Register Contents:
The contents of the registers should be loaded again to restore the state of the process before the interrupt occurred. This is important because the registers may have been altered during the execution of the ISR.
Condition Codes:
The condition codes do not need to be loaded again because they are not changed during the execution of the ISR.
Stack Contents:
The stack contents should not be loaded again because the stack is not modified during the execution of the ISR.
Return Addresses:
The return addresses should be loaded again, as the processor should know where to return to after the ISR has completed.
Therefore, the correct answer is option 'D' - i.e., register contents and condition codes should be loaded again after the interrupt service.
