This value is used to correct the carrier frequency offset of the incoming IF signal. Automatic
frequency control in FM mode can be implemented by registers
A DCO frequency offset (in two’s complement format) is added to the pre-programming value
by AUTOTSD in the CARFQ2 registers (corresponding to the standard IF carrier frequency).
The programmable carrier offset ranges from -192 kHz to +190.5 kHz with a resolution of
1.5 kHz.
For standard FM deviation, the value displayed by register
