MPU Clock Control Register (MPUCKCtl): 0xFFA1
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 1MΩ 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.

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.
