A time delayed reset can be accomplished with the addition of CDelay. Figure 5 provides a graph of time delays, for both rising
and falling output waveform edges, as a function of CDelay. If another value of pullup resistance is used, the time delay can be
calculated by using the equation:

where VthMPU is the microprocessor reset input threshold voltage and tp is the propagation delay internal to the MC33464.
