This is the minimum time RESET must be held low by an external pulldown source to set the active pullup flip-flop.
Measured from RESET V OL to (0.8 x V CC ), R LOAD = ∞ .
WDI is internally serviced within the watchdog period if WDI is left unconnected.
The WDI input current is specified as the average input current when the WDI input is driven high or low. The WDI input is
designed for a three-stated-output device with a 10μA maximum leakage current and capable of driving a maximum capac-
itive load of 200pF. The three-state device must be able to source and sink at least 200μA when active.
