The electronic device 100 includes an electronic component E1, a control circuit C, and a memory circuit M. The electronic component E1 can send a trigger signal to the control circuit C. The memory circuit M can store reset corresponding data and reset record data. The control circuit C can perform a reset operation based on the reset corresponding data of the memory circuit M, and can also update the reset record data of the memory circuit M based on the performed reset operation.

In some embodiments, when the electronic component E1 enters a specific state (for example, the temperature is too high, the voltage supply is abnormal, or an error message is generated, etc.), the electronic component E1 sends a trigger signal to the control circuit C. Subsequently, the control circuit C receives the trigger signal sent by the electronic component E1; reads the reset corresponding data stored in the memory circuit M; and performs a reset operation corresponding to the trigger signal according to the reset corresponding data. When the reset operation is completed, the control circuit C writes the data corresponding to the reset operation into the reset record data of the memory circuit M.

For example, taking the electronic component E1 generating an error message as an example, the electronic component E1 sends a first trigger signal corresponding to the error message to the control circuit C. After receiving the first trigger signal, the control circuit C reads the reset corresponding data of the memory circuit M, and compares the first trigger signal with the reset corresponding data. In this case, the control circuit C confirms according to the reset corresponding data whether the reset operation corresponding to the first trigger signal is to restart the electronic component E1 or to control the electronic component E1 to perform a partial reset, that is, part of the circuit in the control electronic component E1 is reset. Set. Further, the control circuit C restarts or partially resets the electronic component E1 according to the first trigger signal and the reset corresponding data, and resets the data corresponding to the restarted or partially reset electronic component E1 (for example, represents the restarted electronic component The operation code of E1, the parameter setting used to restart the electronic component E1 or the time to restart the electronic component E1, the operation code representing the reset part of the electronic component E1, and the reset part of the electronic component E1 used The parameter setting or the time to reset part of the circuit in the electronic component E1, etc.) are written into the reset record data.

The control circuit C receives the trigger signal sent by the electronic component E1 and reads the reset corresponding data stored in the memory circuit M. Then, based on the trigger signal sent by the electronic component E1 and the reset corresponding data, it is confirmed that the reset operation corresponding to the trigger signal is a total reset operation. Therefore, the control circuit C can perform the overall reset operation accordingly. The overall reset operation is to restart all the electronic components of the electronic device 100 that can be controlled by the control circuit C (for example, the electronic component E1) and all the components with control functions The component (for example, control circuit C) will also restart itself.
