CC25000x07: PKTCTRL1 – Packet automation controlBit Field Name Reset R/W Description7:5 PQT[2:0] 0 (000) R/W Preamble quality estimator threshold. The preamble qualityestimator increases an internal counter by one each time a bit isreceived that is different from the previous bit, and decreases thecounter by 4 each time a bit is received that is the same as thelast bit. The counter saturates at 0 and 31.A threshold of 4·PQT for this counter is used to gate sync worddetection. When PQT=0 a sync word is always accepted.4 Reserved 0 R03 CRC_AUTOFLUSH 0 R/W Enable automatic flush of RX FIFO when CRC is not OK. Thisrequires that only one packet is in the RX FIFO and that packetlength is limited to the RX FIFO size.PKTCTRL0.CC2400_EN must be 0 (default) for the CRCautoflush function to work correctly.2 APPEND_STATUS 1 R/W When enabled, two status bytes will be appended to the payloadof the packet. The status bytes contain RSSI and LQI values, aswell as the CRC OK flag.1:0 ADR_CHK[1:0] 0 (00) R/W Controls address check configuration of received packages.SettingAddress check configuration0 (00) No address check1 (01) Address check, no broadcast2 (10) Address check, 0 (0x00) broadcast3 (11) Address check, 0 (0x00) and 255 (0xFF) broadcastPRELIMINARY Data Sheet (Rev.1.2) SWRS040A Page 57 of 83
