Controls phase of DAC outputs
PHASE[0] = 0 inverts phase of DAC1L output
PHASE[1] = 0 inverts phase of DAC1R output
PHASE[2] = 0 inverts phase of DAC2L output
PHASE[3] = 0 inverts phase of DAC2R output
PHASE[4] = 0 inverts phase of DAC3L output
PHASE[5] = 0 inverts phase of DAC3R output
DAC channel soft mute enables
DMUTE[0] = 1, enable soft-mute on DAC1
DMUTE[1] = 1, enable soft-mute on DAC2
DMUTE[2] = 1, enable soft-mute on DAC3
DAC channel master soft mute. Mutes all DAC channels
