Renesas Starter Kit for RX140

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 E2
Lite debugger. An E2 Lite debugger is supplied with this RSK product.
For further information regarding the debugging capabilities of the E2 Lite debuggers, refer to E2 emulator Lite
User's Manual (R20UT3240EJ), E1/E20/E2 Emulator, E2 Emulator Lite Additional Document for User's
Manual (R20UT0399EJ).
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 128k 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 Boot Modes (SCI and FINE), which are configured on the RSK board.
Details of the modifications required can be found in section 6.2. All other MCU operating modes are
configured within the MCU's registers, which are listed in the RX140 Group User's Manual: Hardware.
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 E2 Emulator Lite (as supplied with this RSK) supports break points, event points (including mid-execution
insertion) and basic trace functionality. It is limited to a maximum of 8 on-chip event points, 256 software
breaks and 256 branch/cycle trace. For further details, refer E2 Emulator Lite User's Manual (R20UT3240EJ).
8.5 Address Space
For the MCU address space details, refer to the 'Address Space' section of RX140 Group User's Manual:
Hardware.
