A watchdog timer (WDT) reset is generated when the watchdog timer times out.
Each core has its own WDT instance. When the application core gets a WDT reset, the network core is held in reset, see Network Force-OFF. A WDT reset in the network core will only cause the network core to reset. The reset target depends on the core where WDT is instantiated.
Note: Because the network core WDT reset is local for the network core, the
application core is not aware of WDT timing out in the network core. Notifying the
application core is possible. One way is to check the register RESETREAS
for WDT flags and report the error through inter-processor communication (IPC).
For more information about WDT, see WDT — Watchdog timer. More information about IPC is available in IPC — Interprocessor communication.
