53 / 66 page  Production Data WM9711L w PD Rev 4.1 April 2004 53 Register 12h controls the output signal of the auxiliary DAC. REG ADDR BIT LABEL DEFAULT DESCRIPTION REFER TO 15 A2H 1 (mute) Mutes AUXDAC to headphone mixer path 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 12h 0 AXE 0 (0FF) Enables AUXDAC Auxiliary DAC Register 14h controls the side tone paths. REG ADDR BIT LABEL DEFAULT DESCRIPTION REFER TO 15 STM 1 (mute) Mutes microphone to headphone mixer path 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 14h 9:7 ALCVOL 010 (0dB) Controls gain of ALC to headphone mixer path Audio Mixers, Side Tone Control 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 15 MU 1 (mute) Mutes OUT3. 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 16h 5:0 OUT3VOL 000000 (0dB) OUT3 volume Analogue Audio Outputs Register 18h controls the audio DACs (but not AUXDAC). REG ADDR BIT LABEL DEFAULT DESCRIPTION REFER TO 15 D2H 1 (mute) Mutes DAC to headphone mixer path 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 18h 4:0 RDACVOL 01000 (0dB) Controls right DAC input gain to all mixers Audio DACs Register 1Ah controls the record selector and the ADC to phone mixer path. REG ADDR BIT LABEL DEFAULT DESCRIPTION REFER TO 14 BOOST 0 (OFF) Enables 20dB gain boost for recording 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 1Ah 2:0 RECSR 000 (mic) Selects right ADC signal source Audio ADC, Record Selector |
