timeout period, then momentarily pulses high, resetting
the watchdog counter. When WDI is left unconnected,
the watchdog timer is cleared by this internal driver just
before the timeout period is reached (the internal driver
pulls WDI high at about 94% of t
WD
). When WDI is
three-stated, the maximum allowable leakage current of
the device driving WDI is 10μA.
In normal mode (WDS = GND), the watchdog timer
cannot be disabled by three-stating WDI. WDI is a
high-impedance input in this mode. Do not leave WDI
unconnected in normal mode.
