When this pin is Low or leaves Open, L-ch data and R-ch
data is input in time-division from Pin 15.
When this pin is High, L-ch data is input from Pin 15, and
R-ch data is input from Pin 14.

When Pin 1 is Low or leaves Open:
Functions as L-R judgment signal input pin.
When Pin 1 is High:
Functions as input data word judgment signal input pin.
When Pin 1 is Low or leaves Open:
Functions as pin to select L-R polarity for LRCK signal.
When LRCK signal is High, set LRSEL pin to Low to input
L-ch data; When LRCK signal is LOW, set LRSEL pin to
High to input L-ch data.
When Pin 1 is High:
Functions as R-ch serial data input pin.
When Pin 1 is Low or Open:
Functions as L-ch and R-ch serial data input pin
alternately.
When Pin 1 is High:
Functions as L-ch serial data input pin.
Input pin for read clock of serial input data
