Notes:
(3)
WDI is internally serviced within the watchdog period if WDI is left open.
(4)
The WDI input current is specified as an average input current when the WDI input is driven high or low. The WDI input if connected to a
three-stated output device can be disabled in the tristate mode as long as the leakage current is less than 10A and a maximum
capacitance of less than 200pF. To clock the WDI input in the active mode the drive device must be able to source or sink at least 200A
when active.
