The microcontroller is widely used in many devices, which works in environment. The microcontroller has to face the challenges from EMI, voltage stability, crystal failure and much other interference. If the interferences are strong enough to disturb the operation, the system design should be secure enough to deal with these matters, one good practice is to reset and go on with previous normal operation state . However, a simple reset is not enough at all. I will demonstrate the basic principle for the system reset and state restore. Please keep in mind that the terminologies used in this article may come from different microcontrollers.Read more...
