13.3.5 I²C decode results
When the configuration of the serial bus is complete, the signal can be decoded:
1. Open the "Serial Bus" dialog for the respective bus.
2. In the "Setup" tab, enable "State".
3. In the "Display" tab, enable "Show decode table".
For a description of the display settings, see also Chapter 13.1.3, "Display",
on page 288.
The instrument captures and decodes the signal according to the standard definition
and the configuration settings.
The color-coding of the various protocol sections and errors simplifies the interpretation
of the visual display. The decode information condenses or expands, depending on the
horizontal scale. Various data formats are available to show the result values.
