other values reserved.
rw 0
0 Æ normal mode, a single packet is sent
1 Æ continuous mode, send multiple packets across the FIFO
(used for spectral analysis)
rw
0x01
0 Æ LNA gain set by register LnaGain
1 Æ LNA gain set by the internal AGC loop
rw 0x00 RX Time-Out MSB
RX Time-Out LSB
RX operation time-out value expressed as number of symbols:

See Section for more details.
0x8 Preamble Length LSB
Payload length in bytes. The register needs to be set in implicit
0x1 header mode for the expected packet length. A 0 value is not
permitted
Maximum payload length; if header payload length exceeds
0xFF value a header CRC error is generated. Allows filtering of packet
with a bad size.
0x0
Symbol periods between frequency hops. (0 = disabled). 1st hop
always happen after the 1st header symbol
n/a
Current value of RX databuffer pointer (address of last byte
written by Lora receiver)
n/a Reserved
