Interpreting I2S Lister Data
In addition to the standard Time column, the I2S Lister contains these
columns:
• Left Channel — displays the left channel data.
• Right Channel — displays the right channel data.
• Errors — highlighted in red and marked with an "X".
Aliased data is highlighted in pink. When this happens, decrease the
horizontal time/div setting and run again.
Searching for I2S Data in the Lister
The oscilloscope's search capability lets you search for (and mark) certain
types of I2S data in the Lister. You can use the [Navigate] key and controls
to navigate through the marked rows.
1 With I2S selected as the serial decode mode, press [Search].
When the receiver word size is greater than the transmit word size, the decoder fills the
least significant bits with zeros and the decoded value does not match the trigger value.
