This register is not used under normal operating conditions.
For ASK/OOK modulation, the recommended settings for operation over the full input range are peak response = 2, leak factor = 10
(default), and AGC delay =10 (default). Bit DB31 to Bit DB16 should be cleared. For bit-rates below 4kbps the AGC_Wait_time can
be increased by setting the AGC_Delay to 15. The SEQ_CLK should also be set at a minimum.
See the Internal AFC section to program the AFC scaling coefficient bits.
The AFC scaling coefficient bits can be programmed using the following formula:
AFC_Scaling_Coefficient = Round ((500 × 2
