Figure 3.32 Trace Window (SH-4A Series)
This window displays the following trace information items:
[PTR]
Pointer in the trace buffer (0 for the last executed instruction)
[Cycle]
Total number of instruction execution cycles (cleared by pipeline reset)
[Address]
Program counter value
[Code]
Executed instruction code
[Pipeline]
Pipeline execution status
Each symbol has the following meaning:
F: Instruction fetch
P: Instruction pre-decode (SH-4A series only)
D: Instruction decode
E: Instruction execution
M: Memory access
W: Write back
Refer to the software manual of each device for more information on
pipeline operation. When a functional simulator is in use, there is no pipeline
information. In this case, x will be displayed here. If the pipeline information
exceeds the display space (the right edge of the [Pipeline] column), the
display continues from the start (the left edge) of the column.
