4.10.2 Enhanced WDT
Enhanced Watchdog Timer
4.10.2.1 Introduction
The Enhanced WDT is a timer counting cycles of a separate on-chip 128kHz oscillator. The Enhanced WDT gives an interrupt or a system reset when the counter reaches a given time-out value. In normal operation mode, it is required that the system uses the WDR - watchdog timer reset - instruction to restart the counter before the time-out value is reached. If the system doesn't restart the counter, an interrupt or system reset will be issued.
