Notes
1.1
Line Assembly
Regardless of the Radix setting, the default for line assembly input is decimal. Specify H as the
radix for a hexadecimal input.
1.2
Event Setting
1.
TAB order in Set Event Status dialog box
Even when you press [TAB] key, the next input control may not be focused on the Set Event
Status dialog boxes opened from H/W Break, Time Measurement, and Trace Point.
2. In-place-edit mode on event list
On event list in H/W Break, Time measurement and Trace Point, High-performance Embedded
Workshop will not escape from in-place-edit mode even when you press the [ESC] key.
3. Event setting by BIT SYMBOL
When the specified address is odd numbers, the setting by BIT SYMBOL can not set the
correct condition. Use DATA ACCESS setting and specify the compared data with the data
mask. For details about how to set the conditions for odd number addresses, refer to the online
help.
4. Event detection for BIT SYMBOL
When the event is set to detect the access to specified bit, it will be detected even if the other
bit of the same address as the specified bit is accessed. This is because the access to the bit
from MCU is byte access.
1.3
1.
1.4
Data Trace
Split-bar behavior when double-clicking
If you double-click the split-bar, which divides view up and down, the horizontal scroll-bar,
vertical scroll-bar, and tabs in the upper view will vanish. Drag the split-bar to display them
again.
Trace
1.
Specifying function in SRC mode
In the SRC mode, when you specify a function to display it, if the current displayed source file
includes the function, the top of the source file will be displayed.
2. Saving of tracing result in text
When you save a tracing result in text with only “BUS” and “DATA” buttons ON, the vertical
position of some headers will shifts from the corresponding data. Check “Tab Separated
Format” and open it with spreadsheet applications to display them correctly.
3. Loading the trace image file
Trace window can not load the trace image file saved by PDxx debuggers. And also, trace
window can not load the trace image file saved by the different target from the current target.
1.5

1.6

1.7
RAM Monitor
Proportional Fonts
When a proportional font is selected, a part of the characters in the view may be hidden. Fixed
fonts are recommended.
Memory
8 bytes data operations
To set, fill, and copy 8 bytes data are not supported.
Script
1.
Result of interactive command
When you invoke an interactive command, for example, Assemble and setMemoryByte, the
running dialog box will appear and may hide the view of the results.
2. SCOPE Command
When you refer current scope name with SCOPE command after program execution, the scope
Rev.1.00 Aug.16.06 page 2 of 6
REJ10J1400-0100
of the start-up module will be returned even if scope has been changed to the other.
1.8
Real-time OS debugging functions
1.
When you use the feature to issue system-calls by the script command (MR SYS), the target
program should be built with a specific option. For details, refer to the topic “Prepare the realtime OS debug” in the online help.
2.
When you use the task pause function, the following code should be inserted to the
configuration file of your target program. For details, refer to the user’s manual of the realtime OS.
// System Definition
system {
:
task_pause = yes; // Insert this line
};
3.
The task pause function uses the address match interrupt of the target MCU. When the target
program uses the address match interrupt, the task pause function can not be used.
4.
The script command “MR STK, BASE” assigns one coverage area so that the area includes the
top address of the system stack area. When you need to check the coverage of other areas,
don’t use the “MR STK, BASE” command and use the “CoVerage BASE” command to assign
coverage area instead. The system stack area and each task stack area will be displayed by
the script command “MR STK, SYS” and “MR STK, TASK”.
1.9
Macro recording function
The debug windows which support the macro recording function are memory, registers, and IO.
And also, the debug operations which support this are Reset CPU, Go, Reset Go, Go To Cursor, Step
In, Step Over, Step Out, Add/Delete a break point, and Download the target program.
1.10
Test facility function
The contents to be compared by the test facility functions are memory, registers, I/O, Output, and
stack trace window.
1.11
Using cast operators for the member variable
When you use cast operators for the member variable to refer to it as the pointer of the structure,
you would not refer to it correctly.
1.12
Download module dialog box
This debugger does not support the setting of "Offset", "Memory verify on download", and "Access
Size" in the download module setting dialog box. These are always treated as "Offset: 0", "Memory
verify: off", and "Access Size: 1".
1.13
Real-time execution of the target program
If the following operations are invoked while the target program is running, the real-time
execution capability will be lost.
! Dump memory
- update the display of Memory Window
- update the display of ASM Watch Window or C Watch Window
- update the display of Source Window (DIS or MIX mode)
- display the value of variables in Source Window
! Clear access history in RAM Monitor Window
! Change the ram monitor area in RAM Monitor Window
! Add or remove software break points
! Change the status of hardware break points

Notes on Debugging (M32C PC4701 Emulator Debugger)
1.14.1 In the case of using PC4701M with IAR’s cross tools
When you have all the following conditions at once, the IAR’s cross tools may not work correctly.
- Using the PC4701M in ECP mode of LPT connection
- The M16C PC4701 emulator software running
1.14.2 About the self-check function
In using the self-check function, if you connect the PC4701 emulator with PC via LAN interface,
the self-check may fail to diagnose the emulator. When you use the self-check function, please use
another communication interface except LAN interface.
1.14.3 About LAN communication with emulators by Windows Me, Windows 98 Windows
XP or Windows2000
It is necessary for LAN communication with emulators by Windows 2000, Windows Me or
Windows 98 to set the following registry.
1. When using Windows Me or Windows 98
Key
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MS
TCP\SackOpts
Value
0 (REG_SZ)
2. When using Windows XP or Windows 2000
Key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\
Parameters\SackOpts
Value
0 (REG_DWORD)
You can set this registry by executing the registry setup program, "Sack.exe". And you can clear
the registry with running the program "UnSack.exe".
- Sack.exe", the program setting the registry.
- Unsack.exe", the program clearing the registry.
The above programs are installed under the directory "\Utility" in the directory where the
emulator software is installed.
(Ex. C:\ Renesas\HEW\Tools\Renesas\DebugComp\Platform\PDTarget)
When using Windows XP/2000, make sure Sack.exe and UnSack.exe are executed by a user who
has Administrator rights. Users without Administrator rights cannot set the registry.
Supplementary:
Windows Me/98/CP/2000 TCP supports "Selective Acknowledgments (SACK)" as documented in
RFC 2018. SACK gives higher performance in the network which have high bandwidth and long
round-trip delays like satellite channels. SACK support is enabled by default in Windows
Me/98/CP/2000. It is necessary for LAN communication with emulators by Windows Me/98/CP/2000
to disable SACK support. Setting the above registry can disable SACK support.
Note that when you use the network which have high bandwidth and long round-trip delays like
satellite channels, the performance with SACK support disabled is lower than with enabled.
