Specify the trace cycle No. within the range of 0 to 32767. An error results if this limit is exceeded.
For reasons of the S5U1C33104H operation timing, the trace data at the boundary of operations, such as in the
fetch cycle at which trace starts or the execution cycle at which trace ends, will not always be stored in
memory.
After a single-step execution or a break occurs, information of the pre-fetched instructions that have not been
executed are displayed. When the target program execution is suspended by a software PC break, the fetch
cycle information of the brk instruction that was inserted for the software PC break is also displayed.
When the program starts a successive execution from an address set as a software PC break point, the
S5U1C33104H executes single-stepping before starting the successive execution. Therefore, redundant trace
information pre-fetched by the single-stepping may be displayed.
For source-level step execution, the S5U1C33104H repeats single-stepping internally. Therefore, a lot of
pre-fetch information of all the steps will be displayed.
Trace data for read/write of the internal RAM cannot be referred since the bus access is undetectable.
During data transfer by the high-speed DMA, data cannot be traced properly.
Specify the trace cycle No. within the range of 0 to 131071. An error results if this limit is exceeded.
In ICD mode, the debugger analyzes trace data based on the 4-bit information delivered from the CPU using
the disassembled program information. Therefore there are some restrictions. Refer to "ICD trace operation
and precautions" in Section 16.9.7 for details.
Once you execute the td command, data can be displayed successively with the [Enter] key only until some
other command is executed.
When you hit the [Enter] key, the [Trace] window is scrolled forward one full screen.
When displaying data in the [Command] window, data is displayed for the 16 lines (default) following the
previously displayed address.
The direction of display is such that each time you input the [Enter] key, data on older execution cycles is
displayed (FORWARD). This direction can be reversed (BACKWARD) by entering the [B] key. To return
the display direction to FORWARD, input the [F] key. If the [Trace] window is open, the direction in which
the window is scrolled is also changed.
(Data on cycle Nos. 115 to 100 is displayed.)
(Data on cycle Nos. 99 to 84 is displayed.)
(Data on cycle Nos. 84 to 69 is displayed.)
(Data on cycle Nos. 99 to 84 is displayed.)
Error: Trace range (0-32767).
Error: Trace range (0-131071).
