CHAPTER 2  DEPENDENCE FUNCTIONS
2.5.6.4
Display Format of Trace Data
The trace data display format can be selected by running the SHOW TRACE command 
with a command modifier specified. If setup is completed with the SET SOURCE 
command so as to select a source line addition mode, a source line is attached to the 
displayed trace data.
There are three formats to display trace data:
• Display without analyzing trace data (Specify /RAWDATA.)
• Display in instruction execution order (Specify /INSTRUCTION.)
• Display in source line units (Specify /SOURCE.)
■
Display without Analyzing Trace Data (Specify /RAWDATA.)
The frame output by the emulator is not analyzed and it displays it as it is.
The display of the source is done and corked in this mode regardless of the setting by the SET SOURCE
command.
Special frame is as follows.
Break at "address":
Displays address which program execution is stopped.
Trace ON code(data) hit:
Indicates that trace acquisition is started.
Trace OFF code(data) hit:
Indicates that trace acquisition is stopped.
