RX_DDC_BAND0_
NCO1_FMULT[21:
16]
R/W
0h
Frequency shift corresponding to the fcw of nco1 of band0,
expressed in kHz, less the closest multiple of Fadc/16. Value
programmed here should correspond to the nco1 fcw of
band0, and should be a value between [-Fadc/32 and
+Fadc/32]..
The System Configuration Macros automatically compute and
configure this, and are hence strongly recommended.
