Watchdog - find out which reload register has triggered reset.

[Al Bundy]

Is to possible to check in watchdog interrupt function which one of the enabled reload registers has triggered the reset?

Hi AlBundy,

as far as I know there is no way to identify which Reload Register(RR) that was not reloaded.

The WDT timeout will occur if one of the registers enabled in RREN is not reloaded with value 0x6E524635. After the WDT timeout you will be able to see that the RESETREAS register indicates that the device was reset by the WDT, but not which RR that was not reloaded.
