REG ADDR BIT LABEL DEFAULT DESCRIPTION REFER TO 12h 15 A2H 1 (mute) Mutes AUXDAC to headphone mixer path Auxiliary DAC 14:12 A2HVOL 010 (0dB) Controls gain of AUXDAC to headphone mixer path 11 A2S 1 (mute) Mutes AUXDAC to speaker mixer path 10:8 A2SVOL 010 (0dB) Controls gain of AUXDAC to speaker mixer path 7 A2P 1 (mute) Mutes AUXDAC to phone mixer path 6:4 A2PVOL 010 (0dB) Controls gain of AUXDAC to phone mixer path 0 AXE 0 (0FF) Enables AUXDAC Register 14h controls the side tone paths. REG ADDR BIT LABEL DEFAULT DESCRIPTION REFER TO 14h 15 STM 1 (mute) Mutes microphone to headphone mixer path Audio Mixers, Side Tone Control 14:12 STVOL 010 (0dB) Controls gain of microphone to headphone mixer path 11:10 ALCM 11 (mute both) Selects ALC to headphone mixer path. 00=stereo, 01=right only, 10=left only, 11=mute both left and right 9:7 ALCVOL 010 (0dB) Controls gain of ALC to headphone mixer path Register 16h controls the analogue output pin OUT3, and also contains one control bit that affects LOUT2 and ROUT2. REG ADDR BIT LABEL DEFAULT DESCRIPTION REFER TO 16h 15 MU 1 (mute) Mutes OUT3. Analogue Audio Outputs 10:9 OUT3SRC 00 (-HPOUTL) Selects source of OUT3 signal. 00=-HPOUTL, 01=VREF, 10=HPOUTL+HPOUTR, 11=-MONOOUT 8 SRC 0 (spkr mix) Selects source of LOUT2 and ROUT2 signals. 0=from speaker mixer, 1=from headphone mixer 7 ZC 0 (disabled) Zero-cross enable 5:0 OUT3VOL 000000 (0dB) OUT3 volume Register 18h controls the audio DACs (but not AUXDAC). REG ADDR BIT LABEL DEFAULT DESCRIPTION REFER TO 18h 15 D2H 1 (mute) Mutes DAC to headphone mixer path Audio DACs 14 D2S 1 (mute) Mutes DAC to speaker mixer path 13 D2P 1 (mute) Mutes DAC to phone mixer path 12:8 LDACVOL 01000 (0dB) Controls left DAC input gain to all mixers 4:0 RDACVOL 01000 (0dB) Controls right DAC input gain to all mixers Register 1Ah controls the record selector and the ADC to phone mixer path. REG ADDR BIT LABEL DEFAULT DESCRIPTION REFER TO 1Ah 14 BOOST 0 (OFF) Enables 20dB gain boost for recording Audio ADC, Record Selector 13:12 R2P 11 (mute) Controls ADC to phone mixer path. 00=stereo, 01=left ADC only, 10=right ADC only, 11=mute left and right 11 R2PBST 0 (OFF) Enables 20dB gain boost for ADC to phone mixer path 10:8 RECSL 000 (mic) Selects left ADC signal source 2:0 RECSR 000 (mic) Selects right ADC signal source |
