When this terminal is "Low" or open, data in L-ch and R-ch is input through pin
15 in time-division. When "High", data in L-ch is input through pin 15 and data
in R-ch through pin 14 respectively.
(Output is pulled-down through a resistor of 100 kohms in IC.) (GND)

Power supply terminal to analog section. (+5V)
Reference voltage terminal. Normally connected to A.GND via capacitor so that an
impedance of high frequency data is lowered.
L-ch analog signal output terminal.
GND terminal for analog section.
When pin 1 is “Low” or open, input data L/R discrimination signal is input.
When “High”, input data word discrimination signal is input.
When pin 1 is "Low" or open, L or R channel is selected for the LRCK signal.
When the LRCK signal is "High" and L-ch data is input, the LRSEL terminal is
“Low”. When “Low” and L-ch data is input, the LRSEL terminal is "High".
When pin 1 is "High", R-ch serial data is input. (+5V)
When pin 1 is "Low" or open, L-ch and R-ch serial data is input alternatively.
When "High", L-ch serial data is input.
Serial input data read-in clock input terminal.
