Note: 1. Parameters of room temperature guaranteed by production test and parameters of full-temperature guaranteed by design.
2. Valid for both RESET and RESET. V RST is the Reset threshold voltage when V CC from high to low level, V RN is nominal
reset threshold voltage.
3. WDI is internally serviced within the watchdog period if WDI is left unconnected.
