3.8
The emulator acquires the results of each instruction execution into the trace buffer as trace information and
displays it in the [Trace] window. The conditions for the trace information acquisition can be specified in the
[Trace Acquisition] dialog box.
Since trace information in bus-cycles is acquired by the hardware circuit and stored in the trace buffer, the
realtime operation is retained. The [Trace] window displays the content of the trace buffer, which records up to
128-k bus cycles from the last program run and is always updated.
Note: For notes on the trace functions, refer to section 5.6, Trace Functions.
3.8.1
To open the [Trace] window, choose [View -> Code -> Trace] or click the [Trace] toolbar button (
3.8.2
When the emulator does not set the acquisition condition of the trace information, all bus cycles are acquired by
default without any condition (free trace mode).
In the free trace mode, trace acquisition is started with the execution of the user program and stopped by halting
the user program. The acquired trace information is displayed in the [Trace] window.
This window displays the following trace information items:
[PTR]:
[Address]:
[Code0]:
[Code1]:
[Data]:

Acquiring Trace Information
Cycle number in the trace buffer. When the most recent record is record 0, earlier
record numbers go backwards (-1, -2, ...). If a delay count has been set, the cycle
number where the trace stop condition has been satisfied is record 0. For the cycle
(during delay) executed until the trace has stopped, earlier record numbers go forward
(+1, +2, ...) the most recent record.
Address bus value (8-digit hexadecimal)
Upper 16 bits of the executed instruction code
Lower 16 bits of the executed instruction code
Data in byte, word, or longword units, displayed as 2-digit, 4-digit, or 8-digit
hexadecimal
