(55) SUBG control register (BBSUBGCON)
This register is used to control the SubGHz transceiver.
The FEC enable bit for reception is used to enable FEC (CODE) of reception.
The FEC mode switch bit is used to switch the FEC encode mode.
The number-of-CRC-bit switch bit is used to switch the number of bits for the CRC calculation process upon
transmission. Note that the number of the CRC bits of the receive frame is used for those upon auto-ACK
reply.
The DW enable bit is used to enable the data whitening upon transmission.
The PHR transmit bit 1 is used to transmit bit 1 of the PHR upon transmission.
The PHR transmit bit 2 is used to transmit bit 2 of the PHR upon transmission.
The interleaving enable bit is used to enable the interleaving. Set INTERLEAVEEN bit to 1 to use FEC.
The BBSUBGCON register is set by the serial interface in 8-bit units.
Reset signal generation sets this register to 0CH.
