MON08 Mode
MON08 Debug Mode supports application development and debug using the internal HC08
monitor. MON08 mode is available to the user through an external MON08 debug cable con-
nected to the 16-pin MON08 header. Alternately, a Serial MON08 interface is provided
through the DEBUG 9-pin DSUB connector. The steps below describe using the external
MON08 debug cable connected to the 16-pin MON08 header.
1. Connect auxiliary equipment to board as required by application.
2. Install and launch P&E PKG08Z tool set, CodeWarrior Development Studio, or other soft-
ware capable of communicating with the HC08 MCU.
3. Configure the board option jumpers for MON08 mode.

NOTE:
The USER5 feature (POT) connects to a
monitor mode configuration line. To ensure proper
monitor mode entry, remove the USER5 jumper.
NOTE:
To enter Monitor Mode, voltage applied at TB1 must 9V.
4.
Connect power to terminal block TB1. Apply voltage b9V and +20V.
5. Hosting development software will establish MON08 communication.
SOFTWARE DEVELOPMENT
Software development will require the use of an HC08 assembler or compiler and a host PC
operating a MON08 debug interface. Supplied with this board is the CodeWarrior Develop-
ment Studio for HC(S)08 along with the Axiom MON08 IDE for Windows for Debugging and
Flash programming.
A powerful source code generation tool called DriveWay™ is also provided on the support CD.
This can generate C source code for the HC08 microcontroller peripherals, based on setup.
See the DriveWay

readme.txt file for more information.
