This value determines the ratio of the MPU master clock frequency to
the VCO frequency (MCLK) such that
MPUClk = MCLK/(2 * (MPUCKDiv(5:0) + 1)).
Do not use values of 0 or 1 for MPUCKDiv(n).
Default is 0Ch to set CPCLK = 3.6923MHz.

The oscillator circuits are designed to connect directly to standard parallel resonant crystal in a Pierce
oscillator configuration. Each side of the crystal should include a 22pF capacitor to ground for both
oscillator circuits and a 1M resistor is required across the 12MHz crystal.
The CPU clock is available as an output on pin CPUCLK.

Note: The crystals should be placed as close as possible to the IC, and vias should be avoided.
