Clock Characteristics
16.4.1
Accuracy of Calibrated Internal Oscillator
It is possible to manually calibrate the internal oscillator to be more accurate than default factory calibration. Note
that the oscillator frequency depends on temperature and voltage. Voltage and temperature characteristics can be
Notes:
1. Accuracy of oscillator frequency at calibration point (fixed temperature and fixed voltage).
