Note 5: WDI is internally serviced within the watchdog 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. The WDI input is
Note 3: This is the minimum time RESET must be held low by an external pull-down source to set the active pull-up flip-flop.

designed for a three-stated-output device with a 10µA maximum leakage current and capable of driving a maximum capaci-
tive load of 200pF. The three-state device must be able to source and sink at least 200µA when active.
