1 Overview

1.1 Main Features

The SK-S12(X) and ZK-S12(X) Series Starter Kits are full-featured, ready-to-

use evaluation boards for the Freescale HCS12(X) family. The Starter Kits

have been designed for the evaluation and the debugging of user

applications.

The Starter Kits take advantage of CodeWarrior Development Studio (which

groups an Editor, Assembler, C Compiler and Debugger) and the Freescale

BDM interface, which allows the download and debug of the user application

into the microcontroller’s FLASH memory.

Together with CodeWarrior, the Starter Kits provide you with everything you

need to write, compile, download, in-circuit emulate and debug user code.

Full-speed program execution allows you to perform hardware and software

testing in real time. The Starter Kits are connected to the host PC through a

USB interface. A prototyping area allows you to wire your own small

application.

Note: on ZK Series, a ZIF (Zero Insertion Force) socket is

provided which allows easy microcontroller insertion/extraction.

The Starter Kits offer you the following benefits:

 Real-time code execution;

 In-circuit debugging;

 In-system programming and debugging through a BDM-compatible

interface;

 Demo area with push-buttons, potentiometer, DIP-switches and user

LEDs;

 Where available: RS-232 ports, CAN transceivers, LIN transceivers and

other target-specific peripherals;

 CodeWarrior for HC(S)12 Development Studio, Special Edition, with

editor, assembler, C compiler and debugger.

Note: this user’s manual explains methods and procedures

common to all of the SK-S12(X) and ZK-S12(X) Series Starter Kits.

For a detailed list of the hardware features of your specific Starter

Kit, please refer to the Starter Kit’s specific user’s manual,

available in PDF format on the SofTec Microsystems’ “System

Software” CD-ROM.

1.2 Background Debug Module (BDM)

All MCUs in the HCS12(X) family contain a single-wire background debug

interface which supports in-circuit programming of on-chip non-volatile

memory and sophisticated non-intrusive debug capabilities. This system

does not interfere with normal application resources. It does not use any

user memory or locations in the memory map and does not share any on-

chip peripherals. The background debug module (BDM) uses a single-wire

communication interface to allow non-intrusive access to target system

memory and registers.

The Starter Kits feature a USB to BDM interface which allows the host PC to

communicate with the microcontroller through a standard USB cable.

Contrariwise to traditional in-circuit emulation (where the target application is

executed and emulated inside the emulator), the Starter Kits use the very

same target microcontroller to carry on in-circuit execution. This means that

all microcontroller’s peripherals (timers, A/D converters, I/O pins, etc.) are

not reconstructed or simulated by an external device, but are the very same

target microcontroller’s peripherals. Moreover, the Starter Kits’ debugging

approach ensures that the target microcontroller’s electrical characteristics

(pull-ups, low-voltage operations, I/O thresholds, etc.) are 100% guaranteed.
