Flexible Clock Mode Settings
If flexible master clock mode is used (VFREQ_EN = 1), the according register settings
can be calculated as follows (a windows-based program for automatic calculation is
available, see
table below.
1. PLL_M and PLL_N must satisfy the equations:
a. 1.5 MHz
b. If a. is not possible, set MCLK_LOW and fulfill
1.02 MHz
c. 65 MHz
(as high as possible within this range)
2. Selection of best dividing mode:
f
f
If the target frequency cannot be reached exactly, the dividing mode has to be selected
to reach a frequency that is as near as possible to the target frequency.
3. Calculation of correction value (frequency mismatch correction)
PHD_E1 = 6
PHD_T1 = 6
The result of these equations is between -2048 and +2047. Negative values are
represented in 2s-complement format (e.g., -2000
