Question

Suppose an 80286 microprocessor is in protected mode. How it is switched back

to real address mode operations.

Answer 1

hardware-initiated reset

Step-by-step explanation:

In order to properly switch it back to real address mode operations you need to perform a hardware-initiated reset. This is because once in protected mode the 80286 will remain there until the hardware itself is reset. Therefore manually reseting the hardware will allow the user to switch back the microprocessor into a real address mode operations.
