In I
data is transferred during the LOW frame sync. The MSB data is sampled first. The data is latched on the second
rising edge of BCLK following a frame sync transition (FS). I
(0x04) to “10” 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”
