To use address, data, and status values in trace
expressions
•
Enter the value(s) desired in the entry buffer (such as address
1000h). Then Choose Trace→After(), Trace→Before(), or
Trace→About(), as desired.
•
Using the command line, enter commands as follows:
•
To specify an address expression, enter:
<expression> -or- address <expression>
•
To specify a data expression, enter:
data <expression>
•
To specify a status expression, enter:
status <expression>
Many trace commands require that you enter address, data and status
expressions to specify the bus state. You can combine multiple expressions
on the same command line to build a complete bus state qualifier. You can
also use logical operators to build more complex states. Refer to the
"Emulator/Analyzer Interface Commands" chapter for details.
The default expression type is address, therefore you don't need to specify
the address keyword when you enter an address expression.
Example
Start a trace and store only writes of 0 hex to the graph address in the demo
program:
trace only graph data 0 status write
