TERMINOLOGY
This development module uses option select jumpers to configure default board operation.
Terminology for application of the option jumpers is as follows:
Jumper – a plastic shunt that connects 2 terminals electrically
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.

FEATURES
The APS12DT256SLK is an educational development module supporting the Freescale
MC9S12DT256 microcontroller (MCU). Application module SLK’s include components for out-
of-box operation and are preprogrammed with a serial monitor to make application
development quick and easy. A background DEBUG port is provided for development tool use
and is compatible with HCS12 BDM interface cables and software. The 60-pin connector
allows the APS12DT256SLK module to be connected to an expanded evaluation environment
such as the Microcontroller Project Board Student Learning Kit (PBMCUSLK) or user’s custom

GETTING STARTED
Please refer to the APS12DT256SLK Quick Start Users Guide to quickly setup the stand-alone
application module or PBS12DT256SLK Quick Start Users Guide to get started with the
microcontroller project board (PBMCUSLK).
OPERATING MODES
The APS12DT256SLK board operates in two operating modes: Run Mode, or Debug Mode.
Run Mode allows user application code to execute from Power-On or Reset. Debug Mode
supports the development and debug of application code. See the related sections below for
quickly starting the board in the desired operation mode.
RUN MODE
Run mode allows user application to execute when power is applied to the board. Use the
following settings to configure the APS12DT256SLK board for RUN Mode to get started
quickly.
1. Connect a COM port serial communication cable between board and host PC if needed for
the application. Launch supporting host communication software as needed.
2. Connect auxiliary equipment to board as required by application.
3. Apply power to the board.
4. The programmed application should begin to execute.
Freescale Semiconductor 7

DEBUG MODE
Debug Mode supports application development and debug. Debug mode is available to the
user through the factory loaded serial monitor, integrated USB-BDM on the PBMCUSLK or an
external HC(S)12 BDM cable. Refer to the PBMCUSLK User Guide for details on using the
integrated USB-BDM.
The steps below describe the steps to put a device in debug mode using the serial cable OR
BDM options.
1. Install and launch the latest CodeWarrior Development Studio.
2. Configure Application specific components. Set jumpers, connect auxiliary equipment to
the module, connect COM port, and launch supporting host communication software, as
needed by the application.
A DB9 serial communications (COM) cable supports the use of serial programming. The steps
below describe using a serial DB9 cable with CodeWarrior for programming and debug.
i. Power-On the device.
ii. Connect COM port serial communication cable between application module and host
PC.
iii. Press and hold simultaneously SW1 and RESET push buttons.
iv. Continue holding SW1 while releasing RESET. Wait 3 seconds, and then release
SW1. The serial monitor is now waiting for the development software to establish
DEBUG communication.
v. Verify that your CodeWarrior debug target is HCS12Serial Monitor.
A 6-pin BDM interface header (BDM_PORT) supports the use of an external HC(S)12 BDM
cable. The steps below describe using an external HC(S)12 BDM cable to access DEBUG
mode.
i. Connect the HC(S)12 BDM cable to the BDM_PORT header.
ii. Connect the supplied USB cable between an available USB port on the host PC and
the USB connector on the board.
iii. Verify that your CodeWarrior debug target is “P&E MultiLink/Cyclone” (or as required
by your hardware selection).
3. Compile project and execute debugger in CodeWarrior. The development software will
establish the DEBUG communication.
NOTE
Upon hardware RESET, the device will default to RUN mode. You will need to do parts of the
above steps to get the hardware back in to DEBUG mode.

DEVELOPMENT SUPPORT
SOFTWARE DEVELOPMENT
Software development will require the use of an HC(S)12 assembler or compiler and a host PC
operating a debug interface. Supplied with this board is the CodeWarrior Development Studio
along with the Axiom IDE for Windows for debugging and flash programming.
MEMORY MAP
The APS12DT256SLK is designed to support the MC9S12D family of MCU’s specifically the
MC9S12DT256. This section shows the default memory map for both MCU’s immediately out
of reset. Refer to the Device User Guide for the specific MCU installed for further details.
Table 1: DT256 Memory Map

0x03FF Registers 1K bytes Mappable to any 2K block in the first 32K
0x0400 –
0x0FFF EEPROM 4K bytes Mappable to any 4K block. Bottom 1K used by Registers out of reset

BDM_PORT HEADER
A 6-pin BDM port header allows connection of a HC(S)12 compatible BDM cable for
application development. Refer to the BDM cable documentation for details on use of the
BDM cable with this module.

EXPANDED MODE OPERATION
For the APS12DT256SLK module, expanded mode operation is supported and available to the
user. All signals necessary to implement the multiplexed bus are available at connector J1.
The MODE option header is used to configure the module for expanded bus mode operation.
Refer to the 9S12DT256 Device User Guide for details on implementing the expanded bus.
MODE
By default, the MC9S12DT256 MCU’s are configured for single-chip operation. The MODE
option header allows the user to configure the board for expanded bus operation. In default
configuration, this header is not installed in default configurations.

MODA 1 2 Shunt pulls MODA input high
MODE
NOTE: Expanded bus mode operation is supported only when a 9S12DT256 MCU is installed
on the MCU.
POWER
The APS12DT256SLK is designed to be used with and powered from the PBMCUSLK. The
APS12DT256SLK will source power from the PBMCUSLK through connector J1. The module
may also be used as a stand-alone platform. As a stand-alone platform, the module may be
powered through the 2.1mm barrel connector and on-board regulator or through connector J1.
The module may also be configured to provide power to external circuitry connected to J1.
When powering external circuitry, do not exceed the maximum output current limit of the on-
board regulator.
