The minimum reset circuit of Figure 14 is not ade-
quate when the
ST10F168 itself during software or watchdog trig-
gered resets, because of the capacitor C1 that will
keep the voltage on
end of the internal reset sequence, and thus will
triggered an asynchronous reset sequence.
Figure 14 shows an example of a reset circuit. In
this example, R1C1 external circuit is only used to

wired-OR gate connection to the reset pin and
may be replaced by open-collector schmitt trigger
buffer. Diode D2 provides a faster cycle time for
repetitive power-on resets.
R2 is an optional pullup for faster recovery and
