Over-temperature limits are guaranteed by design and not production tested.
The RESET short-circuit current is the maximum pullup current when RESET is driven low by a μP bidirectional reset pin.
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 to drive a three-stated output device with a 10μA maximum leakage current and a maximum capacitive load of
200pF. This output device must be able to source and sink at least 200μA when active.
