I2S Trigger and Serial Decode
This section covers triggering and decoding I2S signals. Please read the following for more details:
"I2S Signal Settings", "I2S Trigger" and "I2S Serial Decode".
16.9.1 I2S Signal Settings
Connect the WS, BCLK, and Data signals to the oscilloscope, set the mapping relation between
channels and signals, and then set the threshold level of each signal. The process of specifying the
source and threshold is similar to "I2C Signal Settings"
BCLK
In addition to specifying the source and the threshold level, BCLK signals also require the specification
of the Edge Select .
Rising– Data latched on the rising edge of the clock.
Falling– Data latched on the falling edge of the clock.
WS
In addition to specifying the source and the threshold level, WS signals also require the specification
of the Left CH .
Low– Select the left channel when WS is low and the right channel when WS is high.
High– Select the right channel when WS is low and the left channel when WS is high.
The method of copying settings is the same as I2C signal settings. See "I2C Signal Settings" for
details.
