The internal crystal oscillator uses the external quartz crystal as the basis of its frequency reference.
The frequency of the internal crystal oscillator is divided by 16 and then multiplied by the PLL.
The VCO within the PLL operates over a range of 200 to 400 MHz.
Its output is scaled by a divide
