+3 f res to -4 f res

f res :

315, 433 MHz bands: 2.5 kHz

868 MHz band: 5 kHz

915 MHz band: 7.5 kHz

Bit 3 (st) : Strobe edge, when st goes to high, the actual latest calculated frequency error is stored into the offset register of the AFC block.

Bit 2 ( fi ):

Switches the circuit to high accuracy (fine) mode. In this case, the processing time is about twice longer, but the measurement

uncertainty is about the half.

Bit 1 ( oe ): Enables the frequency offset register. It allows the addition of the offset register to the frequency control word of the PLL.

Bit 0 ( en ): Enables the calculation of the offset frequency by the AFC circuit.
