Reset Switching Threshold
The present default value is typ. 4.65 V. When using the TLE 4263 the reset threshold
can be set to 3.5 V <
The calculation can be easily done since the reset adjust input current can be neglected.
If this feature is not needed, the pin has to be connected to GND.

Watchdog Timing
The frequency of the watchdog pulses has to be higher than the minimum pulse
sequence which is set by the external reset delay capacitor
according to the formula given in
