Serial data interface
The STA339BW audio serial input was designed to interface with standard digital audio
components and to accept a number of serial data formats. STA339BW always acts as 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 I
and figure that follow.
