摘要： A system reset circuit and a method for resetting a system automatically according to an operation state of the system are provided. The system reset circuit includes a system, which is triggered by a first logic state during an operation of a program and a second logic state at termination of the program, for generating a trigger signal for maintaining the first logic state in a lockup state and a counter for receiving the trigger signal as an enable signal, for counting a period of the first logic state of the trigger signal, and for clearing the counting for a period of the second logic state, and of which an output node is connected to a reset node of the system, wherein, when the first logic state period of the trigger signal is maintained before the counter expires, the system generates a reset signal automatically.
