Reset Method for Single-Chip and Single-Chip Computer Systems

摘要

Embodiments of the present invention provide a single chip computer system and a single function that realize both functions of wake up or reset without increasing system resources by determining whether to wake up or reset a single chip computer by detecting the reset pulse width of the reset pin. A reset method for a chip computer system is disclosed. The single chip computer system includes a reset pin, a controller, a CPU and a peripheral device, the single chip computer system is connected to the main control system through one end of the reset pin, and the other end of the reset pin is connected to the controller, The control unit is connected to the CPU and the peripheral device, respectively, the main control system controls the reset pin to output a reset level, the control unit detects the signal duration of the reset level output by the reset pin, Triggering a wake-up or reset of a single-chip computer depends on the signal duration of the reset level, and the signal duration for the wakeup trigger and the signal duration for the reset trigger are different.
