Ground.
The +5V power supply input.
RESET/STROBE (Bidirectional). The open drain goes active if:
1. V
DD
falls below 4.5V nominal.
2. If pulled low by an external electronic signal or switch closure.
3. If the watchdog is not strobed within the minimum watchdog timeout period.
4. During power-up and power-down.
In the input mode, RS connects to a voltage level shift network (typically a resistor divider
to V
DD
.) The watchdog timer is reset when processor causes a voltage level
≤

to be
applied to RS.
