5. Debugging Functions
5.14.8 Detecting a Trace Memory Overflow
Overflows of the trace memory (4 M cycles) can be detected as errors.
(1) Action taken when a trace memory overflow is detected
The following actions are selectable.
- Display a warning.
When the Trace memory overflow checkbox has been selected on the Exception Warning page of the Configuration properties
dialog box, you will see a warning in the Status window and in a status bar balloon when errors of this type occur.
- Make the detection of a trace memory overflow a condition of a hardware breakpoint.
5.14.9 Detecting Task Stack Access Violations
This facility is only available when a load module that includes an OS has been downloaded. The emulator detects an error
when one task attempts writing to the task stack for another task.
(1) Initial settings when the emulator is booted up
At the time the emulator is booted up, the checkbox labeled “Automatically set address areas at downloading” is selected
(flagged by a check mark). However, automatic selection does not proceed until a program is downloaded, because there is no
address information before this.
(2) Action taken when a task stack access violation is detected
The following actions are selectable.
- Display a warning.
When the Task stack access violation checkbox has been selected on the Exception Warning page of the Configuration
properties dialog box, you will see a warning in the Status window and in a status bar balloon when errors of this type occur.
- Make the detection of a task stack access violation a condition of a hardware breakpoint.
- Make the detection of a task stack access violation a condition of a trace point.
