R/W Sync-word qualifier mode.
The values 000 and 100 disables preamble and sync word transmission in
TX and preamble and sync word detection in RX.
The values 001, 010, 101 and 110 enables 16-bit sync word transmission in
TX and 16-bits sync word detection in RX. Only 15 of 16 bits need to match
in RX when using setting 001 or 101. The values 011 and 111 enables
repeated sync word transmission in TX and 32-bits sync word detection in
RX (only 30 of 32 bits need to match).
000 No preamble/sync
001 15/16 sync word bits detected
010 16/16 sync word bits detected
011 30/32 sync word bits detected
100 No preamble/sync, carrier-sense above threshold
101 15/16 + carrier-sense above threshold
110 16/16 + carrier-sense above threshold
111 30/32 + carrier-sense above threshold
