I2S Trigger (Option)
In I2S trigger, the oscilloscope searches for the specified data value and take it as the
condition for identifying the trigger. You need to specify the serial clock line (SCLK, 1
pulse is found on the clock line once 1 bit of digital audio data is sent), frame clock
line (WS, used for switch the audio channel data), and serial data line (SDA, used for
transmit audio data represented in binary (2's complement)).
Below is the sequential chart of I2S bus.
