when changing the value of the internal oscillator calibration bits. 
1. Switch to a different clock source. 
2. Disable the oscillator by writing OSCICN.7 to 0. 
3. Change OSCICL to the desired setting. 
4. Enable the oscillator by writing OSCICN.7 to 1.

Internal Oscillator Calibration.
Factory calibrated to obtain a frequency of 24.5 MHz. Incrementing this register
decreases the oscillator frequency and decrementing this register increases the
oscillator frequency. The step size is approximately 1% of the calibrated frequency.
The recommended calibration frequency range is between 16 and 24.5 MHz.
