The DDS/Mixer supports input types of cint16, cint32 and cfloat as selected by TT_DATA. Input is only required when TP_MIXER_MODE is
set to 1 (simple mixer) or 2 (dual conjugate mixer).
The output type is also set by TT_DATA. When TP_MIXER_MODE is set to 0 (DDS mode), TT_DATA types of cint16 or cfloat only are supported.
