Trace→Find Then Trigger - HP 68302 User Manual

Chapter 8: Menu Bar Commands
Trace→Find Then Trigger... (ALT, T, D)
Trace→Find Then Trigger... (ALT, T, D)
Traces program execution as specified in the Find Then Trigger Trace dialog
box.
This command lets you set up a two level sequential trace specification that
works like this:
1
2
3
If any state during the sequence satisfies the Restart condition, the sequence
starts over.
You can enter address, data, and status values that qualify state(s) by setting
up pattern or range resources. These patterns and range resources are used
when defining the various conditions.
Note
The analyzer traces unexecuted instructions due to prefetching by the 68302
processor.

Once the trace starts, the analyzer stores (in the trace buffer) the states
that satisfy the Enable Store condition while searching for a state that
satisfies the Enable condition.
After the Enable condition has been found, the analyzer stores the states
that satisfy the Trigger Store condition while searching for a state that
satisfies the Trigger condition.
After the Trigger condition has been found, the analyzer stores the states
that satisfy the Store condition.
