3.2.3
The Reset Status Register (RSTST) is a 32-bit read-only register indicating the trigger for the
most recent system reset. The external reset signal (nRST) sets this register to 0x00000000; the
Watchdog Timer (WDT) counter overflow signal (WDTOV), to 0x00000001.
WDTRST
This flag indicates the trigger for the most recent system reset. A "0" indicates the external
reset signal (nRST); a "1," the Watchdog Timer (WDT) counter overflow signal(WDTOV).
