Normal hard reset Delay Time (tPLH) CL : µF Vs CPU : CPU, MPU reset threshold voltage RL : kΩ Voltage : V Note : When VCC line impedance is high, connect a capacitor between IC Pins 1 and 2. 2. Manual Reset Note : Prevent Manual SW chattering by using RL , CL and Rm. Rm setting conditions are as follows : Rm <= 1/20 RL Note : When VCC line impedance is high,connect a capacitor between IC Pins 1 and 2.
