R/W 0h
Frequency shift corresponding to the fcw of nco0 in Mixer2,
expressed in kHz, modulo Fdac/16. Value programmed here
should correspond to the nco0 fcw, and should be a value
between 0 and Fdac/16.
The System Configuration Macros automatically and optimally
partition the overall center frequency between Mixer1 and
Mixer2, and are hence strongly recommended.
