CW Doppler Mode Control
CW_SHDN_CHn is set to 0 in normal operation (default).
Set it to 1 for power-down channel n when in CW Doppler
mode.
Note: The transfer data to AFE procedure described in
be performed twice when setting any CW_SHDN_CHn
bits from 0 to 1 to enable a CW Doppler channel(s). This
procedure only applies to the CW_SHDN_CHn bits; all
other bits are transferred to the AFE in a single operation.
