capacitor (C in pF) employed in the RC network assuming a 45 KΩ external resistor. For
very small values of C, the parasitic capacitance of the oscillator XIN pin and the printed
circuit board must be included in the estimation of the oscillator frequency.
It is possible to operate the RC oscillator using only the parasitic capacitance of the pack-
age and printed circuit board. To minimize sensitivity to external parasitics, external
capacitance values in excess of 20 pF are recommended.

When using the external RC oscillator mode, the oscillator can stop
oscillating if the power supply drops below 2.7 V, but before the power
supply drops to the Voltage Brownout threshold. The oscillator resumes
oscillation when the supply voltage exceeds 2.7 V.
