1. Describe
The STWD100NYWY3F watchdog timer circuit is an independent device that can prevent certain types of hardware errors (for example, unresponsive peripherals and bus contention) or software errors (for example, wrong code jumps and code stuck in loops). ) System failure caused by the STWD100 watchdog timer has an input WDI and an output WDO. This input is used to periodically clear the internal watchdog timer within the specified time-out period twd. When the system is running normally, it will periodically switch the watchdog input WDI. If the system fails, the watchdog timer will not be reset, the system will generate an alarm, and the watchdog output WDO will be asserted. The STWD100 circuit also has an enable pin EN, which can enable or disable the watchdog function. The EN pin is connected to the internal pull-down resistor. If the EN pin is left floating, the device is enabled.
