message "Trace Aborted" will be on screen, along with a listing of the last eight transactions before you
pressed the STOP key .

will show the message "Trace Complete" at the top of the display . The state selected as the trigger will
be on line 0000.
8. Press the LIST key several times. Notice that pressing any of the INPUT DISPLAYS and OUTPUT
DISPLAYS keys switches between the state analyzer and timing analyzer .
9. Press the FORMAT key. Press it a second time, if necessary, to place the [Timing] format specification
on screen .
10 . Check the display of the Activity line . If bit 2 in the timing pod shows no activity, connect bit 2 (the third
line) from the timing probe to any active node in the target system .
11 . Press the TRACE key. See figure 7-5 .
12. Move the cursor into the Pattern field and enter a pattern of XXXX1X1X (with a binary display base) .
