In Left justified interface (normal mode), the left channel serial audio data is synchronized with the frame sync. Left
channel data is transferred during the HIGH frame sync. The MSB data is sampled first and is available on the first
rising edge of BCLK following a frame sync transition (FS). Left justified format is selected by setting AIFMT[1:0]
address (0x04) to “01” binary in conjunction with PCMTSEN[8] address (0x3C) set to LOW.
NAU8812 features a special mode where the device outputs Left channel data to both Left and Right channels. This
is accomplished by setting LOUTR[2] address (0x3C) to “1”
