7.2.1

Serial data interface

The STA381BWS audio serial input was designed to interface with standard digital audio

components and to accept a number of serial data formats. The STA381BWS always acts

as the slave when receiving audio input from standard digital audio components. Serial data

for two channels is provided using three inputs: left/right clock LRCKI, serial clock BICKI,

and serial data 1 and 2 SDI12.

The SAI bits (D3 to D0) and the SAIFB bit (D4) are used to specify the serial data format.

The default serial data format is I2S, MSB-first. Available formats are shown in the tables

that follow.
