Acrobat Reader to view the manuals. Insert the enclosed CD into your computer and SKP installer will auto-start. The SKP installer program will create a C:\Workspace and C:\RENESAS\SKP8CMINI17 folder on your machine. Development tools can be found under C:\RENESAS (NC30WA Compiler, and FoUSB Programmer) and HEW (High-performance Embedded Workshop) is installed into c:\program files.

The ICD can be used to connect to other boards (i.e. customer target boards) with an R8C or M16C Flash MCU. For details, please see ICD User’s Manual included with the kit (Start > All Programs > RENESAS-TOOLS > SKP8CMINI17 > Document Descriptions). 4.4 Development Tools Aside from SKP documentation and sample code, the SKP installer program also installs the development tools.
User programs can run on the Mini R8C board without the host computer running HEW by programming the on-board R8C/Tiny flash MCU with firmware using FoUSB Programmer software and ICD. It can also be used to program other Renesas R8C and M16C Flash MCU’s. SKP8CMINI-17 User’s Manual Rev. 1.1...
The Hardware Manual for the R8C/17 group of microcontrollers can be found on the C:\RENESAS\SKP8CMINI17\Docs folder of your PC under the filename ‘r8c17_hardware_manual_revx.x.pdf’ after SKP software installation or from the Start menu (Start > All Programs > RENESAS-TOOLS > SKP8CMINI17 > Document Descriptions). 5.1.2 Block Diagram The Mini R8C Board incorporates an R5F21174SP (20 pin SSOP) from the R8C/17 group of microcontrollers.
MCU Applications Engineering 5.1.3 External Power Supply Points The external power supply points can be used to operate the Mini R8C Board without power from the ICD. This is a direct connection with Vcc and Ground on the board. Please see the schematic in Appendix C.
MCU Applications Engineering 6.0 System Operation & Limitations The kit provides sophisticated debugging features at a low cost but it does have some limitations when used with the HEW Debugger and ICD. Section 6.1 introduces the ROM monitor program and how it is used. The limitations when this ROM monitor is running with the user program are listed in table 6-1.

HEW or FoUSB Programmer applications. This section also discusses the countermeasures and solutions to resolve these problems. If, for any reason, you cannot resolve the problem, please contact your Renesas representative for assistance. A.1 USB Driver Problems This section discusses the usual problems with the driver installation and how to fix it.
MCU Applications Engineering A.2 Debugging Problems This section discusses the cause of the problem and countermeasures to resolve it. The common problems encountered with debugging are: • Erratic debug behavior • Cannot connect to target • Issues that may come up during debug operations A.2.1 Erratic Debug Behavior HEW allows you to launch multiple “Slave HEW’s”.
