0xFF to the register gives the highest available frequency. The calibrated Oscillator is used to
time EEPROM and Flash access. If EEPROM or Flash is written, do not calibrate to more than
10% above the nominal frequency. Otherwise, the EEPROM or Flash write may fail. Note that
the Oscillator is intended for calibration to 1.0, 2.0, 4.0, or 8.0 MHz. Tuning to other values is not
guaranteed, as indicated in
Table 8-10.
