6 / 12 page TC32M DS21402B-page 6 © 2002 Microchip Technology Inc. 3.4 External Override Reset Control A built-in debounce circuit allows a push-button switch (PB) or other electronic signal to be wire-ORed to this pin as an external RESET override control. The external RESET is required to be an active low signal. Internally, this input is timed to provide a minimum RESET pulse width of 500msec. Reference Figure 3-2. FIGURE 3-2: RS PULLED LOW BY PUSH-BUTTON RESET FIGURE 3-3: POWER UP/DOWN RESET TIMING 3.5 Supply Monitor Noise Sensitivity The TC32M is optimized for fast response to negative- going changes in VDD. Systems with an inordinate amount of electrical noise on VDD (such as systems using relays), may require a 0.01 µF bypass capacitor to reduce detection sensitivity. This capacitor should be installed as close to the TC32M as possible to keep the capacitor lead length short.
