7.1
Overview
For all code debugging using Renesas software tools, the CPU board must be connected to a PC via an
E1/E20/E2 Lite debugger. An E1/E2 Lite debugger is supplied with this RSSK product.
For further information regarding the debugging capabilities of the E1/E20/E2 Lite debuggers, refer to 'E1/E20
Emulator, E2 Emulator Lite - Additional Document for User's Manual' (R20UT0399EJ).
7.2
Compiler Restrictions
The compiler supplied with this RSSK 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.
7.3
Mode Support
The MCU supports Single Chip and Boot Modes (SCI and USB), which are configured on the CPU board.
Details of the modifications required can be found in §6.2. All other MCU operating modes are configured
within the MCU’s registers, which are listed in ‘RX23W Group User’s Manual: Hardware'.
Only ever change the MCU operating mode whilst the MCU is in reset, or turned off; otherwise the MCU may become
damaged as a result.
7.4
Debugging Support
The E1 Emulator or E2 Emulator Lite (as supplied with this RSSK) 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 E1/E20 Emulator User’s
Manual (R20UT0398EJ) or E2 Emulator Lite User’s Manual (R20UT3240EJ).
7.5
Address Space
For the MCU address space details, refer to the ’Address Space’ section of ‘RX23W Group User’s Manual:
Hardware’.
