2.1 RESET Input
Ensure that pin RESET must hold valid-low state during powering-up.
When using a reset IC, use a CMOS type IC. When using an open-drain type reset IC, insert a capacitor
between the reset input and Vss and a resistor between the input and Vcc respectively. The R-C time
constant of the capacitor and resistor must provide a low state at least 10 times longer than the Vcc rise
time.
