GETTING STARTED
The CML-12C32 single board computer is a fully assembled, fully functional development
board for the Motorola MC9S12C32 microcontroller. The board comes with a serial cable,
power supply, and installed binary monitor for stand-alone operation. Support software for this
development board is provided for Windows 95/98/NT/2000/XP operating systems.
Users should be familiar with the hardware and software operation of the target MCU. Refer to
the MC9S12C32 User Manual and Reference Manual for details on MCU operation. The
board’s purpose is to promote the features of the MC9S12C32 and to assist the user in quickly
developing an application in a known working environment. Users should be familiar with
memory mapping, memory types, and embedded software design for quick, successful, appli-
cation development. The user should also be familiar with the various operation modes of the
MCU.
NOTE: With the MCU in expanded mode, the user can not access to Port A, Port B, or Port E.
Application development may be performed by using the embedded binary monitor, or any
compatible MCU BDM cable with supporting host software. The included monitor provides an
effective and low-cost debug method. Note that when a BDM cable is used for debugging, the
BDM pod should be powered from an external supply.
A debug monitor is loaded in the MC9S12C32 internal flash memory and uses some MCU re-
sources for operation. User application may be executed by loading the program start address
into the Reset Vector (0xF7FE, 0xF7FF) and loading the program into device Flash Memory.
The monitor remains in protected flash memory for future use if needed.
Refer to the MC9S12C32 Reference Manual for details on using a BDM pod with the CSM-
12C32 board. Refer to Appendix A for a pin-out of the BDM_PORT connector.
