How this register is used is determined by the FRM bit, which is described below.
FRM = 0 (User Friendly Access)
Bits F[11:0] define the carrier frequency F
automatically to F
FRM = 1 (Direct Access)
F[11:0] defines the receiver local oscillator frequency F
Table 14
frequency value F (in Hz).
Conversely,
frequency registers F[11;0].
