Figure 42. Typical RC Oscillator Frequency as a Function of the External Capacitance with a 45kΩ Resistor
Caution:
When using the external RC oscillator mode, the oscillator may stop oscil-
lating if the power supply drops below 2.7V, but before the power supply
drops to the voltage brown-out threshold. The oscillator will resume oscil-
lation as soon as the supply voltage exceeds 2.7V.
