8. Code Development
8.1 Overview
For all code debugging using Renesas software tools, the RSK board must be connected to a PC via an E8a
debugger. An E8a debugger is supplied with this RSK product.
For further information regarding the debugging capabilities of the E8a debuggers, refer to the R8C Family E8a
Emulator User’s Manual (R0E00008AKCE00E).
8.2 Compiler Restrictions
The compiler supplied with this RSK is fully functional for a period of 60 days from first use. After the first 60
days of use have expired, the compiler will default to a maximum of 64k code and data. To use the compiler with
programs greater than this size you need to purchase the full tools from your distributor.
The protection software for the compiler will detect changes to the system clock. Changes to the system clock back in
time may cause the trial period to expire prematurely.
8.3 Mode Support
The MCU supports Single Chip and Standard Serial I/O modes, which are configured on the RSK board. Details of
the modifications required can be found in §6. All other MCU operating modes are configured within the MCU’s
registers, which are listed in the R8C/LA8A group hardware manual.
Only ever change the MCU operating mode whilst the RSK is in reset, or turned off; otherwise the MCU may
become damaged as a result.
8.4 Debugging Support
The E8a emulator (as supplied with this RSK) supports break points, event points (including mid-execution
insertion) and basic trace functionality. . For more details on breakpoints & E8a functions please refer to the ‘E8A
Emulator User’s Manual’.
