Abstract: A method for forcibly resetting a microcontroller is provided. A switching module is provided to power a microcontroller. The switching module detects through the control pin whether a notification port of a load connected to the control pin changes its potential level in response to a communication error between the load and the microcontroller detected by the load. When the switching module learns the change in the potential level of the notification pin, a powering status of the switching module is switched to stop powering the microcontroller to cause the microcontroller to stop operating. It is detected through the control pin whether the load again changes the potential level of the notification port in response to the microcontroller having stopped operating. When the change is detected, the powering status of the switching module is switched to again power and reactivate the microcontroller.
