●This application note demonstrates how to use the Watchdog module on EFR32 Series 2 devices. For watchdog information regarding EFM32 and EZR32 Wireless MCU Series 0 devices, refer to AN0015.0: EFM32 and EZR32 Wireless MCU Series 0 Watchdog.
●This document discusses initializing the Watchdog, a basic setup for operation, and ways to utilize the added Watchdog functionality in more advanced applications.
●KEY POINTS
■Clock source from selectable oscillators.
■Configurable timeout period.
■Selection to keep running or freeze when entering debug mode.
■Selection to block the CPU from entering EM4.
■Individual selection to keep running or freeze when entering EM2 DeepSleep or EM3 Stop.
■Selection to block the CMU from disabling the selected watchdog clock.
■Advanced features like timeout interrupt without MCU reset, PRS event monitoring or resets, and warning or window interrupt generation.
