1. The host should leave all ‘NC’ (‘no connect) pins unconnected.
2. A—Analog; I—Input; NP—No pull; O—Digital output; OC—Open Collector; PU—Digital input (internal pull up); PD—Digital out-
put (internal pull down); V—Power or ground
3. To avoid adverse effects on module operation, do not draw more than 10 mA current on pin 11.
4. Leave both I2C pins as No Connect if I2C interface is not used.
5. Clock speed: 400 kHz
6. PCM Master/Slave mode and I2S Master mode are supported.
