Data Sheet
7.2.4. Packet Framing
Three options bits located in the general options A register determine the method with which the transceiver will process packets: use
ID, length of packet (LOP) enable and cyclic redundancy check (CRC) enable. An additional bit in the TX config register enables the
buffered TX mode of operation.

X means that the register value is ignored (suggest setting the register to 0X00).
Value means that the TX and the RX device will use default packets of length of this register plus 1 Byte.
Optional means:
General Options B; 1 means that LOP will not be transmitted but the Default LOP will be used
0 means that the LOP will be transmitted
TX Config; 1 means that the Chip ID is transmitted
0 means that the Global Broadcast ID will be transmitted
