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
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.
The reset timeout period is adjustable to accommodate
a variety of µP applications. Adjust the reset timeout
