|
Caution 1. | The trace memory is cleared when you change the setting of this property. |
Caution 2. | When [Data priority] is selected, the function to stop tracing ([Stop trace] in the [Operation after trace memory is full] property) is not usable. |
(4) | [Clear trace memory before running] |
Select whether to clear (initialize) the trace memory before tracing starts.
Select [Yes] to clear the memory (default).
Remark | You can forcibly clear the trace memory when clicking the 
button in the toolbar in the Trace panel. |

Select the operation after the trace memory is full with the collected trace data from the following drop-down list.
|
Non stop and overwrite to trace memory
|

When the [Clear trace memory before running] property is set to [Yes], at the time of a resumption, trace data is collected after clearing the trace memory.
|
|
Stop trace
|
When the trace memory is full, CS+ stops writing trace data (the program does not stop execution).
|
|
Stop
|
When the trace memory is full, CS+ stops writing trace data and the program stops execution.
|
Caution | The trace memory is cleared when you change the setting of this property. |
Select the range of trace data to be collected from the following drop-down list.
Note, however, that this property can be changed only when connected to the debug tool.
|

|
|
Traces out of range
|

|
Caution | If this property is changed, then all trace start and trace end events currently being set will become invalid. |
Remark | When [Traces out of range] is selected, the range of trace data to be collected will be determined by a lower-limit address and an upper-limit address that are specified with a trace start event and a trace end event. |
Caution 1. | For an out-of-range trace event, be sure to specify the start and end addresses. |

Caution | The trace memory is cleared when you change the setting of this property. |
