OSCICL Oscillator Calibration Bits.
These bits determine the internal oscillator period. When set to 00000000b, the oscillator
operates at its fastest setting. When set to 11111111b, the oscillator operates at its slow-
est setting. The reset value is factory calibrated to generate an internal oscillator fre-
quency of 24.5 MHz.
