DCXO Coarse Frequency DAC Adjustment.
64 steps. See Table 8 on page 15 for step size. An increase in CDAC
results in a lower oscillating frequency. Likewise, a decrease in CDAC
results in a higher oscillating frequency.
000000 = Highest frequency
...
111111 = Lowest frequency
Read as zero.
Si4134T Revision (read only).
