Figure 14.10 I2C Decoding Event Table
TIP
•
When you adjust the horizontal time base, the waveform displayed on the screen will also
change, and the total number of lines containing the decoding information in the event
table will also be changed.
•
The displayed decoded data information in the bus is related to the value of the
horizontal time base. Reducing the horizontal time base can help you view the detailed
information.
Set the Event Table Format
In the Decode menu, click or tap the drop-down button of Format to select the
display format of "Data" in the event table. The available options include "Hex",
"Dec", "Bin", or "ASCII".
Address information in decoding
For I2C bus, each frame of data starts with the address information (read address and
write address). In the address information, "Read" indicates the read address
(
) and "Write" indicates the write address (
). You can decide
whether to include or exclude the "R/W" bit for the address information.
Error expressions in decoding
In I2C decoding, when ACK (acknowledgment) is 1, ACK error occurs. When the
detected ACK is 1, red error report information
(the display form is related to
the value of the horizontal time base) is displayed.
