Note: When setting the Internal Rate parameter, the 2370 may not be able to generate the exact
rate. To calculate the available rates, use this equation:
Rate = Osc (PLL_N/PLL_M) (1/Div)
Where
Ocs = 16384000 Hz, 24704000 Hz, or custom oscillator rate
32 ≤ PLL_N ≤ 254
64 ≤ PLL_M ≤ 128
2 ≤ Div ≤ 65354
and PLL_N, PLL_M, and Div are even numbers
