OUT2L mute:
0 = normal operation
1 = mute
OUT2L volume zero cross enable
0 = Change gain immediately
1 = Change gain on zero cross only
OUT2L and OUT2R volumes do not update
until a 1 is written to either OUT2_VU register
bits.
OUT2L volume:
000000 = -57dB
...
111001 = 0dB
...
111111 = +6dB
OUT2R mute:
0 = normal operation
1 = mute
OUT2R volume zero cross enable
0 = Change gain immediately
1 = Change gain on zero cross only
Enable OUT2R inverting amplifier
0 = disabled
1 = enabled
This register must be set to 0 when using the
non-inverting MIXOUT2R to OUT2R path.
This register must be set to 1 when using the
inverting MIXOUT2R to OUT2R path.
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.
OUT2L and OUT2R volumes do not update
until a 1 is written to either OUT2_VU register

Enable Headphone common mode ground
feedback for OUT2
0 = disabled (HPCOM unused)
1 = enabled (common mode feedback through
HPCOM)
