Watchdog Timer (WDT)
Dolphin Technology provides Watchdog Timer (WDT) IP which is used to prevent system lockup if software becomes trapped in a deadlock by generating a system reset, an interrupt, or an external signal. The IP is programmable by a standard APB Slave peripheral which is used periodically by Software to control the watchdog by writing to it to reset its timeout counters.
