Reset Description

state

-

analog audio input signal for the right speaker

channel

-

analog audio input signal for the left speaker

channel

-

high-Z

supply voltage; operates when

3.0 V < VCC < 5.25 V

interrupt output; active LOW; connect to VCC(I/O)

through a 3.3 kΩ resistor

open-drain output

-

asynchronous reset input, active LOW

input

-

speed selection input for the USB transceiver:

• LOW: USB low-speed

• HIGH: USB full-speed.

when not in use, connect to VCC(I/O) through a

10 kΩ resistor

input

-

suspend selection input for the USB transceiver:

• LOW: normal operation

• HIGH: suspend mode.

when not in use, connect to ground through a

10 kΩ resistor

input

-

supply voltage for I/O interface logic signals

(1.65 V to 3.6 V)

-

selection of SPI or I2C-bus serial interface to

access internal registers:

• LOW: SPI slave interface is selected

• HIGH: I2C-bus slave interface is selected.

The I2C-bus device address is 010 110Xb; here X

is determined by pin 13 (I2C_ADR).

input

-

SPI slave data output; leave this pin open when

I2C-bus is selected

push-pull output

high-Z

SPI_MOSI input — SPI slave data input

I2C_SDA input and output — serial I2C-bus data;

when used as an I2C-bus data, the pad is

open-drain; connect to VCC(I/O) through a 3.3 kΩ

resistor.
