Debug Mode

Debug Mode supports application development and debug. Debug mode is available to the

user through the integrated USB-Multilink BDM or through the use of an external

HCS12/HCS08 BDM cable. Use of the integrated USB-Multilink BDM requires only a host PC

with an available USB port and an A/B type USB cable. A 6-pin BDM interface header

(BDM_PORT) supports the use of an external HCS12 BDM cable. The BDM_PORT header is

not installed in default configuration. The steps below describe using the integrated USB-

Multilink BDM.

1. Connect auxiliary equipment to board as required by application.

2. Install and launch P&E PKGHCS08Z tool set, CodeWarrior Development Studio, or other

software capable of communicating with the HCS12/HCS08 MCU.

3. Configure the board option jumpers for DEBUG mode.

NOTE: Refer to the Development Support section below for details on using an external HCS12 BDM cable.

4. Connect the supplied USB cable between an available USB port on the host PC and the

USB connector on the board.

5. Hosting development software will establish DEBUG communication.

6. Refer to BDM cable documentation for details on use of BDM.

SOFTWARE DEVELOPMENT

Software development requires the use of an assembler or compiler supporting the HCS08

instruction set and a host PC operating a debug interface. CodeWarrior Development Studio

and Axiom IDE for Windows for Debugging and Flash programming are supplied with this

board.

DEVELOPMENT SUPPORT

Application development and debug for the target MC9S08DZ60 is supported through a

background debug mode (BDM) interface. The BDM interface consists of an integrated USB-

Multilink BDM and a 6-pin interface header (BDM_PORT) to connect a HCS12/HCS08 BDM

cable.

Integrated BDM

The DEMO9S08DZ60 board features an integrated USB-Multilink BDM from P&E

Microcomputer Systems. The integrated USB-Multilink BDM supports application development

and debugging via background debug mode. All necessary signals are provided by the

integrated USB-Multilink BDM. A USB, type B, connector provides connection from the target

board to the host PC.

The integrated USB-Multilink BDM provides +5V power and ground to target board eliminating

the need to power the board externally. Power from the USB-Multilink BDM is derived from the

USB bus; therefore, total current consumption for the target board, and connected circuitry,

must not exceed 500mA. This current limit describes the current supplied by the USB cable

to the BDM circuit, the target board, and any connected circuitry. Excessive current drain will

violate the USB specification causing the bus to disconnect. Damage to the host PC USB hub

or the target board may result.

BDM_PORT Header

A compatible HCS12 BDM cable can also attach to the 6-pin BDM interface header

(BDM_PORT). This header is not installed in default configuration. The figure below shows

POWER

The DEMO9S08DZ60 is designed to allow the user to power the board through the USB-

Multilink BDM during application development. A 2.0-mm barrel connector has been applied to

support stand-alone operation and to support LIN functionality. The board may also be

powered through connector J1. This connection may also be used to supply power from the

board to external circuitry.

During application development, the board may be powered from either the USB-BDM or the

PWR connector. To utilize LIN functionality, the board must be powered from PWR connector

with a typical input voltage of +12VDC.

POWER SELECT

Power may be applied to the board through the integrated USB-Multilink BDM circuitry, a

2.0mm barrel connector, or through connector J1. Power selection is achieved using 2

selection headers: PWR_SEL option header and the VX_EN option header.

PWR_SEL

The PWR_SEL option header selects power input either from the integrated USB-Multilink

BDM circuitry or from the on-board voltage regulator. The figure below details the PWR_SEL

header connections.
