TERMINOLOGY
This development board uses option selection jumpers. A jumper is a plastic shunt that con-
nects 2 terminals electrically. Terminology for application of the option jumpers is as follows:
Jumper on, in, or installed - jumper is installed such that 2 pins are connected together.
Jumper off, out, or idle - jumper is installed on 1 pin only. It is recommended that jumpers be
idled by installing on 1 pin so they will not be lost.

SOFTWARE DEVELOPMENT
Software development requires using a ColdFire assembler or compiler and a host PC running
a ColdFire BDM interface. CodeWarrior Special Edition, supplied with this board, allows the
user to develop and debug application code and to program flash.
One method to ensure successful application development is to load and execute the applica-
tion from internal RAM. After the application has been completely debugged, and is fully func-
tional, it can be ported to FLASH. When programmed into FLASH, the application will execute
from Power-On or RESET if the RESET vector is programmed.
OPERATING MODES
The M52233DEMO board operates in two basic modes Run Mode, or Debug Mode. Run
Mode executes user application code from Power-On or Reset, if the RESET vector is pro-
grammed. Debug Mode supports the development and debug of applications via the inte-
grated USB BDM. An optional BDM_PORT is provided but not installed. See the related sec-
tions below for quickly starting the board in the desired mode of operation.
The board has been preloaded with a USB stack and open-source RTOS. Refer to the
GETTING STARTED section of this document for further details.
RUN Mode
Run mode executes the user application out of FLASH when power is applied to the board or
the RESET button is pressed. Of course, the RESET vector must be programmed to allow
application code to execute. Use the following settings to configure the M52233DEMO for
RUN Mode using the USB bus to power the board. See the POWER section below for details
on configuring the board for alternate power input.
1. Connect a serial cable and Ethernet cable between the board and a host PC if required.
2. Connect auxiliary equipment to board if required.
3. Configure the board option jumpers as shown.
Table 2: Run Mode Setup

BDM_EN OFF
COM_EN ALL ON (if required)
VX_EN ON (if required)
LED_EN ON (if required)
4. Connect the USB cable to an open USB port on the host PC and attach to the USB port on
the target board. LED’s D301 and D302 located adjacent to the USB connector, and the

VDD LED will light and the loaded application will begin to execute, if the RESET vector
has been programmed.
Debug Mode
Debug Mode supports application development and debug using the ColdFire background de-
bug module (BDM). Background mode is accessible using either the integrated USB-BDM or
an external ColdFire BDM cable. Using the integrated BDM requires a host PC with an avail-
able USB port and an A/B USB cable and appropriate hosting software. The USB cable must
be USB 2.0 compliant. An external BDM cable can be attached to the 26-pin BDM_PORT
header. However, this header is not installed in default configurations. The steps below de-
scribe using the integrated USB-BDM. See the POWER section below for details on configur-
ing the board for alternate power input.
1. Connect a serial cable and ethernet cable between the board and a host PC if required.
2. Connect auxiliary equipment to board if required.
3. Install and launch CodeWarrior 6.1 Special Edition, or other software capable of communi-
cating with the ColdFire MCU.
4. Configure the board option jumpers as shown.

5. Connect the supplied USB cable between an available USB port on the host PC and the
USB connector on the board. LED’s D301 and D302 located adjacent to the USB connec-
tor, and the VDD LED will light. Hosting development software will establish background
communication.
MEMORY MAP
Refer to the MCF52235 Integrated Microcontroller Reference Manual for details. The latest
version can be downloaded from the Freescale web site at www.freescale.com.
DEVELOPMENT SUPPORT
Application development and debug for the target MCF52233 is supported through the BDM
interface. The debug interface consists of an optional 26-pin header (BDM_PORT) and an in-
tegrated USB-BDM debugger. The BDM_PORT header is not installed in default configuration

but may be installed by the user if needed. Refer to the MCF52235 Integrated Microcontroller
Reference Manual for details on using the Background Debug Module
Optional JTAG access is also supported through the BDM_PORT header. To use this optional
JTAG access, open the cut-trace between pin 1 and pin 2 of the BDM_SEL option header. In-
stall a standard 1x3 header at location BDM_SEL and install a shunt between pin 2 and pin 3.
Refer to the MCF52235 Integrated Microcontroller Reference Manual (www.freescale.com) for
details on using the JTAG port access.
BDM_PORT Header
A ColdFire BDM cable may be attached to the 26-pin BDM_PORT port header. This header is
not installed in default configuration. Its use requires installing a 2x13, 0.1” center, pin-header.
Refer to the BDM documentation, in the device reference manual, for details on using the BDM
cable. The BDM_PORT header pin-out is shown below.

NOTE: This header is not installed in default configuration.
Integrated BDM_PORT
The M52233DEMO board features an integrated USB-BDM debugger. The integrated debug-
ger supports application development and debugging via the background debug mode. A type
B, USB connector provides connectivity between the target board to the host PC.
NOTE: Using the integrated USB BDM requires CodeWarrior 6.1 Special Edition or develop-
ment tools from P&E Microcomputer Systems.
The integrated debugger provides power and ground to the target, thereby eliminating the
need to power the board externally. Power from the integrated USB-BDM is derived from the
USB bus and total current consumption is limited by the USB specification. Total current con-
sumption for the target board, and all connected circuitry, must not exceed 500mA. Excessive

M52233DEMO SEPTEMBER 25, 2006
10
current drain will violate the USB specification causing the bus to disconnect. This will force a
target POR.
CAUTION: Violating the USB specification will cause the USB bus to disconnect forcing the
target to reset.
POWER
The M52233DEMO is designed to allow application development while powered from the
USB_BDM. A 2.0mm barrel connector and a 2-position, screw-type, terminal block (BATT)
has been applied to support stand-alone operation. The board may also be powered through
connector J1. Additionally, the board may be configured to supply power through connector J1
to external circuitry. An OFF/ON switch allows the user to quickly and easily connect and dis-
connect all power sources.
When using the integrated USB-BDM, the board draws power from the USB bus. Excessive
current drain will violate the USB specification causing the USB bus to disconnect forcing a
POR. Total current consumption of the board and connected circuitry, therefore, must be less
than 500mA.
CAUTION: Violating the USB specification will cause the USB bus to disconnect. This will
force a hard reset on the target.
The installed barrel connector accepts a center-positive, 2.1m barrel plug. The terminal block
accepts wire sizes ranging from 28ga to 16ga. Voltage input must be in the range between
+5V and +15V. At no time should input voltage exceed +15V as damage to the board may re-
sult. The terminal block input is connected directly to the upper voltage rail. Input protection is
not applied on this voltage input. The user must exercise caution when using the terminal
block to input power to the board.
Voltage supplied through connector J1 is also connected directly to the board voltage rails. No
protection is applied on this input and the user must exercise caution when powering the board
from connector J1.
CAUTION: Input protection is NOT applied to the J1 or BATT power inputs. Excessive input
voltage or current will damage the board.
POWER JACK
The PWR power jack consists of a 2.1mm, center-positive, barrel connector. Voltage applied
at this connector should range between +5V and +15V.
