6.6.3 RC Oscillator Mode with Internal Capacitor
If both precision and cost are taken into consideration, the EM78P510N also offers a
special oscillation mode, which has a built-in internal capacitor and an external resistor
connected to Vcc. The internal capacitor functions as temperature compensator. In
order to obtain more accurate frequency, a precise resistor is recommended.
