Data Rate Lower Byte.
See formula above. Defaults = 40 kbps.
Reserved.
This bit should be set for Data Rates below 30 kbps.
If set, the Packet Handler will be powered down when chip is in low power mode.
Manchester Preamble Polarity (will transmit a series of 1 if set, or series of 0 if
reset).
This bit affects ONLY the transmitter side, not the receiver. This is valid ONLY if Man-
chester Mode is enabled.
Manchester Data Inversion is Enabled if this bit is set.
Manchester Coding is Enabled if this bit is set.
Data Whitening is Enabled if this bit is set.
