FB_DDC_NCO0_F
MULT[15:8]
R/W
0h
Frequency shift corresponding to the fcw of nco0, expressed
in kHz, modulo Fadc/16. Value programmed here should
correspond to the nco0 fcw, and should be a value between [0
and Fadc/16].
The System Configuration Macros automatically compute and
configure this, and are hence strongly recommended.
