73S1210F Data Sheet
MPU Clock Control Register (MPUCKCtl): 0xFFA1 0x0C
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.
Note: The crystal 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.
