Serial audio interface protocols
The STA333ML serial audio input interfaces with standard digital audio components and
accepts serial data formats. The STA333ML always acts as a slave when receiving audio
input from standard digital audio components. Serial data for two channels is provided using
3 input pins: left/right clock LRCKI (pin 29), serial clock BICKI (pin 28), and serial data SDI
(pin 30).
The available formats are given in
such that FMT = logical 0 gives the I
