9.2.2 Detailed Design Procedure

The primary constraint for this application is the reset delay time. In this case, because CT is open, it is set to 20ms. A 0.1µF decoupling capacitor is connected to the VDD pin and a 100kΩ resistor is used to pull up the RESET pin high. The MR pin can be connected to an external signal if desired.
