Internal Oscillator Enable.
0: Internal oscillator disabled.
1: Internal oscillator enabled.
Internal Oscillator Frequency Ready Flag.
0: Internal oscillator is not running at its programmed frequency.
1: Internal oscillator is running at its programmed frequency.
Read = 001111b. Must Write 001111b.
Spread Spectrum Enable.
0: Spread Spectrum clock dithering disabled.
1: Spread Spectrum clock dithering enabled.
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.
