0
R/W Disable digital DC blocking filter before demodulator.
0 = Enable (better sensitivity for data rates ≤ 250
kbps)
1 = Disable (reduced power consumption)
The recommended IF frequency changes when the
DC blocking is disabled.
000
R/W The modulation format of the radio signal
Setting Modulation format
0 (000) 2-FSK
1 (001) GFSK
2 (010) -
3 (011) OOK
4 (100) -
5 (101) -
6 (110) -
7 (111) MSK
0
R/W Enables Manchester encoding/decoding.
0 = Disable
1 = Enable
010
R/W Combined sync-word qualifier mode.
The values 0 (000) and 4 (100) disables sync word
transmission in TX and sync word detection in RX.
The values 1 (001), 2 (001), 5 (101) and 6 (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 1 (001) or 5
(101). The values 3 (011) and 7 (111) enables
repeated sync word transmission in RX and 32-bits
sync word detection in RX (only 30 of 32 bits need
to match).
Setting Sync-word qualifier mode
0 (000) No preamble/sync
1 (001) 15/16 sync word bits detected
2 (010) 16/16 sync word bits detected
3 (011) 30/32 sync word bits detected
4 (100) No preamble/sync, carrier-sense
above threshold
5 (101) 15/16 + carrier-sense above threshold
6 (110) 16/16 + carrier-sense above threshold
7 (111) 30/32 + carrier-sense above threshold
