Reset delay
; connect a capacitor to ground for delay time
adjustment.
Reset switching threshold
; for setting the switching threshold,
output to ground with voltage divider. If this input is connected to
ground, the reset is triggered at an output voltage of 4.5 V.
Watchdog input
; positive-edge-triggered input for monitoring a
microcontroller.
5-V output voltage;
