In right 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. The data is latched on the
last rising edge of BCLK before frame sync transition (FS). The LSB is aligned with the falling edge of the frame sync
signal (FS). Right justified format is selected by setting AIFMT[1:0] address (0x04) to “00” 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”
