摘要： A semiconductor device includes a monitoring circuit receiving a first supply signal and generating a flag signal by monitoring a second supply signal provided to a monitored circuit; a watchdog circuit disposed in the monitoring circuit, receiving the first supply signal, and generating a watchdog signal; and a comparison circuit receiving the flag signal and the watchdog signal and generating a first signal which has a first level under an abnormal condition and a second level under a normal condition. The second level is different than the first level. The watchdog circuit sets the watchdog signal to a third level when the level of the first supply signal is lower than a first reference level. When the watchdog signal has the third level, the comparison circuit allows the first signal to have the first level regardless of the level of the flag signal.

摘要： A periodic process performing system includes a system processor to which a first periodic real-time process, which starts to be executed starts for each of a first time interval from a first start time, is assigned; a wakeup logic which provides the system processor with a first state capable of executing the first periodic real-time process; and a counter which supplies a first tick signal to the wakeup logic for each of the first time interval from a second start time earlier than the first start time, and supplies a second tick signal to the system processor for each of the first time interval from a third start time between the first start time and the second start time.
