Only 15 of 16 bits needto match in RX when using setting 1 (001) or 5 (101).The values 3 (011) and 7 (111) enables repeated syncword transmission in TX and 32-bits sync worddetection in RX (only 30 of 32 bits need to match).SettingSync-word qualifier mode0 (000) No preamble/sync1 (001) 15/16 sync word bits detected2 (010) 16/16 sync word bits detected3 (011) 30/32 sync word bits detected4 (100) No preamble/sync, carrier-senseabove threshold5 (101) 15/16 + carrier-sense above threshold6 (110) 16/16 + carrier-sense above threshold7 (111) 30/32 + carrier-sense above thresholdPRELIMINARY Data Sheet (Rev.1.2) SWRS040A Page 61 of 83
