When the CS Signal Is ON
The data containing the reference point becomes analysis number 0. However, if the
reference point is between two data points, the first detected data after the reference
point becomes analysis number 0.

Note
If you set the reference point to Trigger Position, the byte containing the trigger point is
analysis number 0. However, if a trigger is activated on the trigger conditions of the SPI Bus
signal, the trigger point is the byte boundary. Hence, the analysis number of the byte on
which the trigger is activated is 0 or –1.
• Data1 and Data2 Values
The Data1 and Data2 values are displayed in hexadecimal. However, below are
some exceptions.
• When the data is less than 8 bits, “–” is displayed.
• CS
Displays the CS signal enable status. Note the following:
• When none of the CS signal is ON, blank is displayed.
• When only one CS signal is ON, the status H or L of the CS signal is displayed.
• Display Example of Analysis Data
Examples of analysis using different analysis conditions are indicated below.
