ELECTRICAL CHARACTERISTICS (continued)
(V
Note 4: This is the minimum time RESET must be held low by an external pulldown source to set the active pullup flip-flop.
Note 5: Measured from RESET V
Note 6: WDI is internally serviced within the watchdog period if WDI is left unconnected.
Note 7: The WDI input current is specified as the average input current when the WDI input is driven high or low. The WDI input is
