Embodiment Construction

[0046] Figure 4 It is a schematic diagram of an electronic device 400 according to an embodiment of the present invention. The electronic device 400 includes a reset control circuit 401 and a system terminal 402 . To put it simply, when the electronic device 400 operates abnormally, the user triggers the reset control circuit 401 to make the system 402 know that it needs to be restarted, so as to eliminate the system crash.

[0047] In this embodiment, the reset control circuit 401 includes a button SW, an anti-bounce circuit 403 , a reset circuit 404 , a soft reset trigger circuit 406 , a delay circuit 405 , and a hard reset trigger circuit 407 .

[0048]The anti-bounce circuit 403 is coupled between the button SW, the soft reset trigger circuit 406 and the delay circuit 405 . Anti-bounce circuit 403 includes capacitor C1. The capacitor C1 is coupled between the button SW and the ground. The reset circuit 404 includes a resistor R1. The resistor R1 is coupled between th...

Abstract

The invention discloses an electronic device, a reset control circuit and a reset control method of the electronic device. The electronic device comprises the reset control circuit and a system end, wherein, the reset control circuit comprises a key, a soft reset trigger circuit, a time-delay circuit and a hard reset trigger circuit. The key receives a triggering signal and outputs the triggering signal when being pressed down. The soft reset trigger circuit is coupled to the key and outputs a soft reset signal to lead the system end to execute soft reset operation when receiving the triggering signal. The time-relay circuit is coupled to the key and outputs the triggering signal after accumulation time of triggering signal receiving reaches a preset time value. The hard reset trigger circuit receives the triggering signal from the time-relay circuit and outputs a hard reset signal to lead the system end to execute hard reset operation when receiving the triggering signal.

Description

technical field [0001] The present invention relates to a soft reset (software reset) and a hard reset (hardware reset) of an electronic device, and in particular to an electronic device, its reset control circuit and method. Background technique [0002] During the use of the existing electronic device, when the user finds that the operation is abnormal, he usually presses the reset button of the electronic device to allow the system to perform an initialization action again. In order to maintain the integrity of the original system data, a soft reset is usually used to notify the main microprocessor of the electronic device to re-execute the program from the initial address. However, the worst possibility is that the system is completely frozen, and a hard reset must be triggered to force the main microprocessor and peripheral chips to operate again. [0003] In order to generate two different reset trigger signals for general electronic devices, usually reset control cir...
