3.3.2. Bit Rate Setting
When using the RF69 in Continuous mode, the data stream to be transmitted can be input directly to the modulator via pin
9 (DIO2/DATA) in an asynchronous manner, unless Gaussian filtering is used, in which case the DCLK signal on pin 10
(DIO1/DCLK) is used to synchronize the data stream. See section 3.3.5 for details on the Gaussian filter.
In Packet mode or in Continuous mode with Gaussian filtering enabled (refer to section 5.5 for details), the Bit Rate (BR) is
controlled by bits BitRate in RegBitrate:
BR =
F
