Note 1: Overtemperature limits are guaranteed by design and not production tested.
Note 2: The reset output is guaranteed to be in the correct state if either VCC3 or VCC5 is within its specified region of operation.
Note 3: The reset output(s) is asserted if either VCC5 or VCC3 drops below its associated trip point.
Note 4: Guaranteed by design. Not production tested.
Note 5: WDI is internally serviced within the watchdog timeout period if WDI is left unconnected.
Note 6: The WDI input current is specified as the average input current when the WDI input is driven high or low.
