WATCHDOG APPARATUS AND CONTROL METHOD THEREOF |
摘要 |
The present invention provides a watchdog apparatus in which a main MCU and a sub MCU are connected by SPI communication, including: a token generating unit which generates a seed value and generates at least two tokens using the seed value; a watchdog signal generating unit which generates a watchdog signal corresponding to the generated token; a signal determining unit which determines whether the generated watchdog signal is in a normal state and thus provides an advantageous effect which may detect an abnormality of the MCU only using a software logic without providing an additional configuration. |
