As guide line for the calculation of the external capacitor at the analog input pin the formula based on the internal
equivalent capacitance and the ADC resolution of the corresponding AD-converter channel can be used:
Cexternal: External capacitor at the analog input pin
CIN: Equivalent input capacitance
ADCresolution: AD-converter resolution for RH850/F1K-2 either 12-bit or 10-bit resolution
