The watchdog can be configured in the SCSR register to either reset the device (WDRST) or assert an interrupt (WDINT), if the watchdog counter reaches the maximum value. The behavior of each condition is:
To avoid unexpected behavior, software must not change the configuration of the watchdog while WDINT is active. For example, changing from interrupt mode to reset mode while WDINT is active immediately resets the device. Disabling the watchdog while WDINT is active causes a duplicate interrupt, if the watchdog is later re-enabled. If a debug reset is issued while WDINT is active, the reset cause register (RESC) shows a watchdog reset. The WDINTS bit in the SCSR register can be read to determine the current state of WDINT.
