433 MHz = 2.5 kHz
868 MHz = 5 kHz
915 MHz = 7.5 kHz
The offset error value is stored in the Offset register (FOREN bit should be enabled) in the AFC block and
is added to the frequency control word of the PLL. Reset this bit before initiating another sample.
In High-Accuracy (Fine) mode, the processing time is twice the regular mode, but the uncertainty of the
measurement is significantly reduced.
FOFEN: Frequency Offset Enable bit
1 = Enables the frequency offset calculation using the AFC circuit
0 = Disables the frequency offset calculation using the AFC circuit
