  • Patent number: 12001850
    Abstract: In order to determine whether a reset function of an electronic device is safe, the states of a first checker and a second checker are toggled to preset states when a reset root is received from an external device. When a release of a local reset is received, whether the local reset was normally released is determined on the basis of a system clock. When the local reset is not normally released, the state of the second checker is toggled, and when the final local reset among the local resets is normally released, the state of the first checker is toggled. The release states of the local resets are monitored on the basis of the state of the first checker and the state of the second checker.
