Note 1. The frequency is affected by a capacitor, a resistor and a microcomputer. So, set the constants within the range of the frequency
limits.
Note 2. If the rising time exceeds the maximum rating value, connect a capacitor between the RESET pin and Vss at the shortest
distance, and input “L” level to RESET pin until the value of supply voltage reaches the minimum operating voltage.
