The Instructions that can run only in User Mode are called Non-Privileged Instructions .
Various examples of Non-Privileged Instructions include:
Reading the status of Processor
Reading the System Time
Generate any Trap Instruction
Sending the final prinout of Printer
Also, it is important to note that in order to change the mode from Privileged to Non-Privileged, we require a Non-privileged Instruction that does not generate any interrupt.
