DAC clock select. A 1-bit value to select the clocks for the DAC
(interpolator and FSDAC analog block). In both cases the clocks must be
128f
the WSI clock, and in the other case the clock is derived from the SYSCLK.
When this bit is logic 0: SYSCLK is used. When this bit is logic 1: WSPLL is
used. Default value 0.
Dividers for system clock input. A 2-bit value to select the proper division
factor for the SYSCLK input in such a way that a128f
from the SYSCLK clock signal. The 128f
decimator and interpolator. Default value 00, see Table 19.
WSPLL setting. A 2-bit value to select the WSPLL input frequency range.
These set the proper divider setting for the WSPLL. The input is the
WSI signal, the output inside the IC is a 128f
value 10, see Table 20.
