This register must be set to 1 when using the inverting MIXOUT2R to OUT2R path. 9 OUT2R_IN V_MUTE 1 Mute output of PGA to inverting amplifier. 0 = PGA output goes to inverting amplifier 1 = PGA output goes to output driver This register must be set to 0 when using the inverting MIXOUT2R to OUT2R path. This register must be set to 1 when using the non-inverting MIXOUT2R to OUT2R path. 8 OUT2_VU 0 OUT2L and OUT2R volumes do not update until a 1 is written to either OUT2_VU register bits. 7:2 OUT2R_VO L [5:0] 11_1001 OUT2R volume: 000000 = -57dB ... 111001 = 0dB ... 111111 = +6dB R76 (4Ch) Output Control 2 OUT2_FB 0 Enable Headphone common mode ground feedback for OUT2 0 = disabled (HPCOM unused) 1 = enabled (common mode feedback through HPCOM) Table 42 Controlling OUT2L and OUT2R |
