Numeric Display Format.

The Numeric display format shows the data of specified

bit width for binary or hexadecimal radix values. When using the numeric
display format, parallel data can be displayed as serial data. Refer to Figure 2-15.

Figure 2Ć15: Numeric display format

The different editing operations are selected from the EDIT 

!

 Execute Action

menu. Press the front panel EXECUTE button to execute the selected operation.
Editing can be accomplished quickly by using the general-purpose knob and the
CURSOR button to move the cursor. Press the EXECUTE button to complete
the process. Figure 2-16 shows the procedure used to select the Invert data
editing operation and invert data bits at three locations.
