Introduction
1 INTRODUCTION
The ST622x Starter Kit provides you with all you need to start designing, developing and evaluating programs for ST620x, ST621x and ST622x microcontrollers immediately. The ST622x Starter Kit includes: * The ST6 assembler and linker, AST6 and LST6. * A demonstration of the ST6 application development tool, ST6-Realizer. * The ST6 Windows debugger, WGDB6. * The Windows ST6 microcontroller programmer, Epromer. * The ST6 Starter Kit board, which serves as a demonstration board and low-cost debugging tool. * Some demonstration programs that show how ST6 microcontrollers use the Starter Kit board resources. * Some example programs for the ST622x family. * Two ST62E25, two ST62E20 and one ST62E01 microcontrollers. * A complete set of paper documentation and online help. The demonstration programs, that come pre-loaded on an ST62E25 microcontroller, show how the powerful features of ST6 microcontrollers operate in a real environment. The demonstration programs use the hardware resources provided on the Starter Kit board, which include reset and data control buttons, LED indicators, a resistance trimmer, temperature control circuit and an RS-232 interface. Using the ST6 assembler and linker, AST6 and LST6, you can assemble and link ST6 programs. The AST6/LST6 User Manual will guide you through the steps of developing, assembling and linking programs for the ST6. The Starter Kit software includes a set of example programs of typical ST6 applications. These are installed in the directory C: \ST622x\examples. For a fast-track solution for developing bug-free programs for the ST6, without the hassle of writing assembler code, try out the ST6-Realizer demonstration. Once you have developed your ST6 program, you can use the Windows-based ST6 program debugger, WGDB6/SIMULATOR, together with the Starter Kit board, as a low-cost but powerful debugging tool. WGDB6 includes an ST6 simulator, that simulates the execution of your program, and uses the ST6 that is plugged into the Starter Kit board to emulate all transactions that are performed with the data space. Thus, using the Starter Kit board with WGDB6, you can view how the microcontroller peripherals behave when your program is executed. WGDB6 includes powerful debugging features, such as source-level debugging, instruction and conditional memory access breakpoints and selective trace recording. The WGDB6 Get-

ting Started manual and online help will lead you through the debugging process using WGDB6. When your program is ready, Epromer provides you with an easy-to-use Windows interface, which lets you prepare executable code, then write it to the ST6 microcontroller that is plugged into either one of the DIL sockets on the Starter Kit board, or your own in-circuit application board that is connected to the Starter Kit board. To observe and evaluate the consequences of your program on the resources it controls, you can run it on an ST6 microcontroller that is plugged into the Starter Kit board. If it controls a resource that is not included on the Starter Kit board, you can connect your own resource to the board.

2.8 Temperature Control Circuit This circuit demonstrates temperature control, using the on-chip A/D converter. A Heater resistor circuit (150, 1 Watt) is driven by the TIMER output of the ST6225 microcontroller. The heat level can be controlled by varying the duty cycle of a PWM signal present on the TIMER output. The Heater circuit can be disconnected from the TIMER output pin by removing the W6-TIMER jumper. A thermistor bridge (Negative Temperature Coefficient) is connected to the PA4 I/O pin, which is programmed as an A/D converter input. The voltage value at the A/D converter input decreases as the thermistor temperature increases. The Thermistor circuit can be disconnected from PA4 by removing the W5 jumper. The thermistor is located in close proximity to the Heater resistor on the Starter Kit board, so that it can be used as a sensor to detect the temperature of the resistor body. Demonstration 6 shows how this circuit is used as a feedback loop that controls the temperature level (see "Running the Demos" on page 16).

The Starter Kit Hardware
2.10 Demonstration Selector Jumpers The demonstration selector is made up of a 6-position jumper W10 (marked 12 on the Starter Kit board diagram on page 9), with each jumper connected to a resistor. Each resistor generates a different voltage. After reset, the voltage value generated by the resistor whose jumper is installed is sent to PA3 on the ST6225. PA3 is programmed as an A/D converter. The program installed on the ST6225 uses the input from PA3 to select the appropriate demo. The following table lists the voltage values generated by each resistor:
Resistor value: RT: 10 K R1: 680 R2: 750 R3: 820 R4: 1 K R5: 1.2 K Theoretical voltage value: No JUMPER: 5 V JUMPER-D1: 0 V JUMPER-D2: 333 mV JUMPER-D3: 666 mV JUMPER-D4: 999 mV JUMPER-D5: 1.332 V
The same principle can be used for keyboard decoding. For a complete example of this, refer to the SGS-Thomson application note: "AN431: Using ST6 Analog Inputs for Multiple Key Decoding". You can disconnect the demonstration selector from PA7 by removing the PA7 jumper from W10 (marked 12 on the Starter Kit board diagram on page 9).

Running the Demos
4 RUNNING THE DEMOS
This section describes the demonstration programs that are provided with the Starter Kit and explains how to run them. 4.1 What the Demos Do The following paragraphs describe the demos that come pre-loaded with the ST6 Starter Kit demos. See "Running the Demonstration Programs" on page 18 below for details on how to select and run a demo. The source files of these demos are provided with the Starter Kit software in the file C:\ST622X\SK622XLI\DEMOK25.ASM. 4.1.1 Demo 1 - Button/LED Indicator Control 1 Initialises the pins as follows:
This pin: PB3 PB4 PA0 to PA3 Is initialised as: Input with pull-up and interrupt. Connected to + button. Input with pull-up and interrupt. Connected to - button. Push-pull outputs. Connected to the four LEDs (as marked on board).
2 Performs a task relating to your actions:
When you do this: Press the + button Press the - button The program does this: Jumps to an interrupt subroutine that lights up each led in turn, from LD4 to LD1. Jumps to an interrupt subroutine that lights up each led in turn, from LD1 to LD4.
4.1.2 Demo 2 - Voltage trimming and LED level indication 1 Initialises the pins as follows:
This pin: PA5 PA0 to PA3 Is initialised as: Analog input. Connected to the trimmer. Push-pull outputs. Connected to the four LEDs (as marked on board).

Running the Demos
2 Reads the A/D converter data register, and turns on a LED according to the Voltage value input by the trimmer: This voltage: 0 to 1 1 to 2 2 to 3 3 to 4 4 to 5 Turns this LED on: none LD1 LD2 LD3 LD4
Adjusting the voltage trimmer (marked 9 on the Starter Kit board diagram on page 9) turns on the appropriate LED. Pressing the + or - buttons has the same effect as increasing or decreasing the voltage. 4.1.3 Demo 3 - Temperature Control 1 Initialises the pins as follows:
This pin: PA4 TIMER PB3 PA0 to PA3 Is initialised as: Analog input. Connected to the thermistor circuit. Push-pull output. Connected to the Heater Resistor circuit. Input with pull-up and interrupt. Connected to + button. Push-pull outputs. Connected to the four LEDs (as marked on board).
2 Reads and stores the A/D converter data register value. This value indicates the temperature at reset. 3 Reads and stores the A/D converter data register value at regular intervals. If this value exceeds the value that was stored at reset, a LED is turned on indicating the difference between the two values. The higher the difference is between the stored value and the read value, the higher LED number is turned on (roughly in steps of LD(n+1) for each additional degree difference). You can either increase the temperature by touching the thermistor (marked 14 on the Starter Kit board diagram on page 9) or pressing the + button.

Running the ST6-Realizer Demo
5 RUNNING THE ST6-REALIZER DEMO
ST6-Realizer is a Windows CASE tool that enables you to develop high-quality applications for the ST6 family of microcontrollers. Using ST6-Realizer, you design your application by drawing symbols and wiring them together. Each symbol represents a process, such as adding two values, and is linked to an ST62 assembly code macro. The wires represent the flow of data, and are linked to variables and constants. You can attach attributes to symbols and wires, in order to attach extra characteristics to them. For example, attaching an attribute of type UINT to a wire defines its value capacity to that of an unsigned integer (0 to 65536). When using ST6-Realizer, you design your application in schemes. A scheme is like a sheet of paper on which you place symbols and draw wires. Each application is designed on one scheme. To install the ST6-Realizer demo: 1 Place the diskette labelled "ST6-Realizer Demo disk" into your floppy disk drive. 2 In Windows Explorer or File Manager, browse the contents of the diskette, and double-click the Install icon. To run the ST6-Realizer demo: If you are using Windows 3.x, double-click the ST6-Realizer demo icon in the ST6 Tools group. If you are using Windows 95, click Start, Programs, ST6 Tools, then the ST6-Realizer demo.

Connecting External Resources to the Starter Kit Board
6 CONNECTING EXTERNAL RESOURCES TO THE STARTER KIT BOARD
You can connect your own external resources to the pre-programmed ST62E25 to debug or evaluate your programs, using the connector J2 (marked 17 on the Starter Kit board diagram on page 9). To be able to connect your own resources to the Starter Kit board, you must disconnect the resources that are already connected to the ST62E25, to avoid external resource/Starter Kit board resource conflicts. The following table lists the Starter Kit board resources and the corresponding J2 connections, and indicates the jumper that disconnects each resource.

Using The Starter Kit Board as a Hardware Simulator
7 USING THE STARTER KIT BOARD AS A HARDWARE SIMULATOR
WGDB6, the ST6 debugger that runs under Windows, lets you test your programs without having to program the EPROM of your target ST6. Depending how much information you want, and how close to real life you want your test environment to be, you can use WGDB6 in one of three ways: * As a software simulator. If you use WGDB6 as a simulator, you need not attach any additional hardware to your PC. The ST6 simulator program, that comes with WGDB6 and is run when you run WGDB6/Simulator, simulates the execution of your program, letting you step through the code and see what happens as the program runs. WGDB6 simulator includes Wave Form Editor, which simulates the output of the pins on your target ST6 in relation to inputs that you define, enabling you to see how its peripherals react to the inputs they receive. * With an ST6 hardware emulator. Emulators are hardware systems that act as your target microcontroller, at the same time capturing detailed information, such as which areas of memory are accessed by the program and what happens when they are accessed. In this case, WGDB6/Emulator provides an interface between the emulator and your PC, displaying data captured by the emulator and letting you implement the WGDB6 features in the emulator, such as software or hardware breakpoints. * With the Starter Kit board as a hardware simulator. This is a cross between the above two. The WGDB6 software simulator simulates the execution of your program, but each time the data space is accessed, it accesses that of the ST6 that is plugged into your Starter Kit board. Thus, using the Starter Kit board with WGDB6, you can view how the real microcontroller peripherals behave when your program is executed. This section describes the third option, how to use the Starter Kit board as a hardware simulator. You can use the Starter Kit board to emulate any ST620x, ST621x or ST622x microcontroller. Note, however that you must use the pre-programmed ST62E25 microcontroller, labelled DEMOK25 supplied with the kit for hardware simulation. Thus, when simulating programs designed for other microcontrollers, make sure that you do not use resources that are not available on the microcontroller your application is designed for.

Using The Starter Kit Board as a Hardware Simulator
7.1 The Data Transmission Driver Data is transferred between the simulated peripheral registers and the ST620x, ST621x and ST622x registers via the host PC's parallel port. The DEMOK25.HEX program, with which the ST62E25 microcontroller that is plugged into the Starter Kit board must be loaded includes the transmission driver. The data transfer driver uses the following bits:
PC parallel port D2 D3 D4 D6 SDOP ST6225 PB2 PB1 RESET NMI PB0 WGDB6 Use Synchronisation Write data to MCU Hardware reset of peripherals Initiates data transfer Read data from MCU
7.2 Technical Limitations The Starter Kit board has the following limitations when used with WGDB6 as a hardware simulator: * Real-time program execution is not supported. * Resetting the ST6225 by power on, pressing the Reset button or external reset does not reset the simulated ST6 core. To perform a complete simulated reset, use the WGDB6 reset command instead. * Interrupts sent by the ST62E25 microcontroller are not supported by the WGDB6 simulator. * The pins: NMI, PB0, PB1 and PB2 on the ST62E25 microcontroller are used for communications with the host PC, and are thus not available for simulation.
NOTE: Do not connect any external resources to the corresponding J2 connector pins when using the Starter Kit board as a peripheral emulator.

8.3 In-Circuit Programming You can perform in-circuit programming of ST620x, ST621x or ST622x OTP/EPROM microcontrollers using your own board, connected to the Starter Kit board via the connector J1 (marked 1 on the Starter Kit board diagram on page 9). 8.3.1 Application Board Connections The following paragraphs specify the connection requirements between your application board and the Starter Kit board. The application board must have a suitable 16-way connector (8x2 header HE10) to be connected via a 16-way cable to connector J1 (marked 1 on the Starter Kit board diagram on page 9) on the Starter Kit board. The following table shows the required pin connections:
ST620x, ST621x and ST622x Pins PB6 PB5 OSCin PB7 RESET VPP/TM VDD VSS Connector Pins Pin 1 Pin 3 Pin 5 Pin 7 Pin 9 Pin 13 Pin 14, 16 Pin 2, 4, 6, 8, 10
VDD Use of the VDD connection is optional, depending on whether the application board supply can or cannot be disconnected. If the application board supply is disconnected, you can supply it through pins 14 an 16 of the connector, as long as the total load current does not exceed 100 mA, and the capacitive load is less than 50 F. If the application board has its own power supply, its voltage must be set to 5V, so that logic levels are compatible with those of the Starter Kit board. OSCin Synchronises the programming operations using a clock generated by the programming tool. OSCin is located on the application board, and must be directly connected to Pin 5 on the 16way connector. No isolation is needed as long as a quartz crystal or ceramic resonator is used in the application. If an external clock generator is used in the application, it must be disconnected during in-circuit programming.

Programming ST6 Microcontrollers
RESET Controls the programming mode entry. To prevent signal level contention, RESET must be directly connected to Pin 9 on the 16-way connector, and must be isolated from other nodes on the application board. Any direct connection to V DD, VSS or an output must be avoided. This pin can be connected to a CMOS input, a 2 K pull-up, a 10 KOhm pull-down or left open (Internal pull-up). The capacitive load of the RESET pin should not exceed 1
F.
Pins 1 and 7 on the 16-way connector are used to establish communications between the programming tool and the microcontroller. To prevent signal-level contention, Pins 1 and 7 must be directly connected to PB6 and PB7 on the 16-way connector, and must be isolated from other nodes on the application board. Any direct connection to V DD, VSS or an output must be avoided. These pins may be connected to a CMOS input, a 2 K pull-up, a 10 KOhm pull-down or left open (Internal pull-up). If pin 3 on the 16-pin connector is connected to the target device, the same applies. Connection to pin 3 is not necessary if a high voltage level is guaranteed by the board design. Some I/O pins are not connected to the 16-way connector and must be set to a high level during programming. This is normally achieved by the RESET signal sent by the programming tool through the 16-way cable, setting the I/O pins as inputs with an internal 300 K pull-up. To keep these I/O lines high, direct connection of these pins to GND or to any other signal at low level (even temporarily) must be avoided. Only connections to another CMOS input, to an external pull-up or a 10 M pull-down is allowed. The signals on PB3 and PB5 (if not directly biased through pin 3 of the 16-way connector) must be kept at a high voltage level. The Vpp/TM pin must not be directly connected to GND/V SS on the application board, to avoid any conflict with the programming voltage provided by the programming tool via pin 13 on the connector. This pin should be pulled down by a resistor with minimum value of 10 K . You must add a 100 nF ceramic capacitor between Vpp/Test and V SS.
