This register will read 0 whenusing OOK modulation.SWRS040B Page 82 of 92
CC25000x33 (0xF3): LQI – Demodulator Estimate for Link QualityBit Field Name Reset R/W Description7 CRC_OK R The last CRC comparison matched. Cleared whenentering/restarting RX mode. Only valid ifPKTCTRL0.CC2400_EN=1.6:0 LQI_EST[6:0] R The Link Quality Indicator estimates how easily a received signalcan be demodulated. Calculated over the 64 symbols followingthe sync word.0x34 (0xF4): RSSI – Received Signal Strength IndicationBit Field Name Reset R/W Description7:0 RSSI R Received signal strength indicator0x35 (0xF5): MARCSTATE – Main Radio Control State Machine StateBit Field Name Reset R/W Description7:5 Reserved R04:0 MARC_STATE[4:0] R Main Radio Control FSM StateValue State name State (Figure 15, page 40)0 (0x00) SLEEP SLEEP1 (0x01) IDLE IDLE2 (0x02) XOFF XOFF3 (0x03) VCOON_MC MANCAL4 (0x04) REGON_MC MANCAL5 (0x05) MANCAL MANCAL6 (0x06) VCOON FS_WAKEUP7 (0x07) REGON FS_WAKEUP8 (0x08) STARTCAL CALIBRATE9 (0x09) BWBOOST SETTLING10 (0x0A) FS_LOCK SETTLING11 (0x0B) IFADCON SETTLING12 (0x0C) ENDCAL CALIBRATE13 (0x0D) RX RX14 (0x0E) RX_END RX15 (0x0F) RX_RST RX16 (0x10) TXRX_SWITCH TXRX_SETTLING17 (0x11) RXFIFO_OVERFLOW RXFIFO_OVERFLOW18 (0x12) FSTXON FSTXON19 (0x13) TX TX20 (0x14) TX_END TX21 (0x15) RXTX_SWITCH RXTX_SETTLING22 (0x16) TXFIFO_UNDERFLOW TXFIFO_UNDERFLOWNote: it is not possible to read back the SLEEP or XOFF state numbersbecause setting CSn low will make the chip enter the IDLE mode fromthe SLEEP or XOFF states.SWRS040B Page 83 of 92
