4.2.2.7
The Oscillator Calibration (OSCCAL) Register is used
to calibrate the internal 4 MHz oscillator. It contains four
bits for fine calibration and two other bits to either
increase or decrease frequency.

CALFST: Calibration Fast
1 = Increase frequency
0 = No change
CALSLW: Calibration Slow
1 = Decrease frequency
0 = No change
If CALFST = 1 and CALSLW = 1, CALFST has precedence.
