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. VRST is the Reset threshold voltage when VCC from high to low level, VRN is nominal
reset threshold voltage.
3. WDI is internally serviced within the watchdog period if WDI is left unconnected.
