IIS
Audio Data Format
The IIS bit is used to select the audio data format, either Standard Right Justified or I
2
S.
IIS = 0
IIS = 1
Standard Right Justified (default)

LRP
LRCK Polarity
The LRP bit selects the polarity of left/right clock input (LRCK) when using the Standard Right Justified audio
data format. This bit has no effect when using the I
2
S audio data format.
LRP = 0
LRP = 1
Left Channel when LRCK = High; Right Channel when LRCK = Low (default)
Left Channel when LRCK = Low; Right Channel when LRCK = High
ATC
Attenuation Mode Control
The ATC bit is used to select independent or common attenuation data for the Left and Right channels.
ATC = 0
ATC = 1
Independent: Left Channel uses Register 0 and Right Channel uses Register 1 (default)
Common: Left and Right Channels both use Register 0
