Microcomputer command load input ("L" level to load)
Reset pin (active "L").
Always pull this pin low after applying the power.
Input format selection pin.
"H" level; I²S format
"L" level; signal processing LSI format.
Digital filter test output pin 1. Leave this pin open.
Digital filter test output pin 2. Leave this pin open.
Digital filter test input pin 1. Keep this pin at "L" level.
Digital filter test input pin 2. Keep this pin at "L" level.
No connection Leave these pins open.
No connection Leave these pins open.

(Ground for oscillator circuit)
Crystal oscillator pin.
Crystal oscillator pin. (External clock input pin)
No connection Leave this pin open.
Power supply pin 2 for analog circuits. (+5V)
Ground pin 2 for digital circuits.
Connect to D-V_DD.
(Silicon substrate potential fixing pin)
Output pin for detecting zero input.
192f_s(=9.216 MHz)output pin.

LRCLK polarity selection pin. "H" level; selects the left channel
"L" level; the right channel.
LRCLK pin. When the LRPOL pin is at "H" level, "H" level in this pin indicates left
channel data input; "L" level indicates right channel data input. When the LRPOL pin
is at "L" level, "L" level in this pin indicates left channel data input; "H" level input
indicates right channel data input.
Serial input bit clock
Serial input data (digital) input pin.
Ground pin 3 for digital circuits.
