STA333W
Serial audio input interface format
Table 16.
Serial data interface
The STA333W audio serial input interfaces with standard digital audio components and
accepts a number of serial data formats. STA333W always acts a 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 SDI.
Bits SAI and bit SAIFB are used to specify the serial data format. The default serial data
format is I
