11. C
11.1. O
Note: For all code debugging using Renesas software tools, the 3DK board must be connected to a PC serial port
via a serial cable.
The HMON embedded monitor code is modified for each specific 3DK Renesas Microcontroller. HMON enables
HEW to establish a serial connection to the 3DK microcontroller, and control code execution on the
microcontroller. The HMON embedded monitor code must be compiled with user software and downloaded to the
3DK, allowing the users’ code to be debugged within HEW. The board must be operated in BOOT mode during
debugging.
11.2. M
The HMON library is built to support Normal Mode only. The Device supports only Normal Mode.
11.3. B
The monitor has an address break controller with one break channel, therefore one breakpoint can be located in
ROM. Code located in RAM may have multiple breakpoints limited only by the size of the On-Chip RAM.
Due to a limitation of the internal address break controller, a breakpoint set in ROM will execute the instruction at
the breakpoint and stop on the subsequent op-code. The break controller only functions in BOOT mode.
11.4. C
Double clicking in the breakpoint column in the code sets the breakpoint. Breakpoints will remain unless they are
double clicked to remove them.
11.5. H
HMON is built along with the debug code. Certain elements of the HMON code must remain at a fixed location in
memory. The following table details the HMON components and their size and location in memory. For more
information, refer to the map file when building code.

HMON Uninitialised data
FDT Init Kernel.
This is at a fixed location and must not be moved. Should
the kernel need to be moved it must be re-compiled.
FDT User Mode Kernel.
This is at a fixed location and must not be moved. Should
the kernel need to be moved it must be re-compiled.
Pointer used by HMON to point to the start of user code.
