Notes 1: The frequency at RC oscillation is affected by a capacitor, a resistor and a microcomputer. So, set the constants within the range of the frequency limits.
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.
