15.4 Packet Length Compliance.
If set, then PK Length definition for both TX and RX will also include the CRC bytes,
If reset, then the Length refers ONLY to the DATA payload. For example, writing ―9‖
to this register when it is set, means we are sending/expecting ―7‖ bytes of DATA,
and the other ―2‖ should be the CRC (CRC should be enabled separately).
Reserved.
Turn Around Enable.
Enabling for the turn around functionality.
Turn Around Phase.
The RX to TX and vice-versa change in frequency will happen (if bit [2] is set) at the
last byte, and these two registers set the bit position in which the frequency shifts
should occur. Make sure it does not happen to early otherwise the last bits will be
missed.
