Note: 1. Parameters of room temperature guaranteed by production test and parameters of full-temperature guaranteed by design.
2. Valid for both RESET and RE SET. VRST (VRTH-) is the Reset threshold voltage when VCC from high to low level, and
VRTH+ is the Reset threshold voltage when VCC from low to high level. VRN is nominal reset threshold voltage.
3. WDI is internally serviced within the watchdog period if WDI is left unconnected.
