Table 14. Minimum Reset Capacitor for a 15k Pull-down Resistor
Note:
These values assume VDD starts from 0v to the nominal value. If the time between two
on/off sequences is too fast, the power-supply decoupling capacitors may not be fully
discharged, leading to a bad reset sequence.
During a Normal
Operation (Warm Reset)
Reset pin must be maintained for at least 2 machine cycles (24 oscillator clock periods)
to apply a reset sequence during normal operation. The number of clock periods is
mode independent (X2 or X1).
Watchdog Reset
A 1K resistor must be added in series with the capacitor to allow the use of watchdog
reset pulse output on the RST pin or when an external power-supply supervisor is used.
Figure 6 shows the reset circuitry when a capacitor is used.

Figure 7 shows the reset circuitry when an external reset circuit is used.
