R/W

Description

DEM_DCFILT_OFF

R/W

Disable digital DC blocking filter before demodulator.

0 = Enable (better sensitivity)

1 = Disable (current optimized). Only for data rates

≤ 250 kBaud

The recommended IF frequency changes when the DC

blocking is disabled. Please use SmartRF

 Studio [5] to

calculate correct register setting.

R/W

Enables Manchester encoding/decoding.

0 = Disable

1 = Enable

2:0

SYNC_MODE[2:0]

2 (010)

R/W

Combined sync-word qualifier mode.

The values 0 (000) and 4 (100) disables preamble and

sync word transmission in TX and preamble and sync

word detection in RX.

The values 1 (001), 2 (010), 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 TX and 32-bits sync word

detection in RX (only 30 of 32 bits need to match).
