Page 11 Hardware Setup Click the “Next >” button. 7. Depending on your Windows settings, the following warning may appear. Note: this warning is related to the fact that the USB driver used by the Demonstration Board is not digitally signed by Microsoft, and i Windows considers it to be potentially malfunctioning or dangerous for the system. However, you can safely ignore the warning, since every kind of compatibility/security test has been carried out by SofTec Microsystems. Click the “Continue Anyway” button. 8. Windows will install the driver files to your system. At the end of the installation, the following dialog box will appear. Page 12 DEMO9S08LC60 User's Manual Click the “Finish” button to exit from the “Found New Hardware Wizard” procedure. 9. The Demonstration Board’s USB driver is now installed on your system. 4.2 Power Supply The Demonstration Board can be powered in three ways: � 12 V DC input connector; � USB connector; � I/O header connector. The “POWER SEL” jumper allows you to power the board through either the 12 V DC input connector or the USB connector. When using the I/O header connector, its pin 1 is always connected to the 3.3 V DC line of the carrier board. Page 13 DEMO9S08LC60 User's Manual 5 Operating Modes 5.1 Overview The Demonstration Board can work in two modes: “standalone” mode and “host” mode. 5.2 Standalone Mode In standalone mode, no PC connection is required. The microcontroller is factory programmed with a sample application which shows the value of the potentiometer on the display. To run the built-in example: 1. Ensure that both the “CLK ENA” jumpers are inserted. 2. Ensure that all of the “IO1” and “IO2” jumpers are inserted. 3. Ensure that all of the “LED ENA” jumpers are inserted. 4. Ensure that both the “g-Sel1” and “g-Sel2” jumpers select the “0” position. 5. Ensure that the “Sleep Mode# SEL” jumper selects the “1” position. 6. Ensure that the “POWER SEL” jumper selects the “USB” position. 7. Power on the board via a USB cable. Alternatively, you can power the Demonstration Board through a 12 V DC plug-in power supply (not included in the kit). In this case, the “POWER SEL” jumper must select the “UNREG” position. 8. The green “POWER” LED on the board should turn on. 9. Rotate the potentiometer. Its value will be shown on the display. 5.3 Host Mode In host mode the program execution is controlled by the host PC through the “USB” connector. You can use the PC to debug the application by, for example, executing the program step by step and watching how the microcontroller registers vary, using the provided CodeWarrior Development Studio. Page 15 Operating Modes Note: all MCUs in the S08 family contain a single-wire background debug interface which supports in-circuit programming of on-chip non-volatile memory. This system does not interfere with normal application i resources. It does not use any user memory or locations in the memory map. The Background Debug Module (also known as Background Debug Controller, BDC) uses a single-wire communication interface (via the BKGD line) to allow non-intrusive access to target system memory and registers. Please note that the BKGD line is shared with the PTC6 line and the RESET line is shared with the PTB2 line. The user program, therefore, must not use the PTC6 line when working in host mode. To work in host mode (using the built-in USB to BDM interface): � Make sure that both the “RESET#” and “BKGD” jumpers in the “IO2 ENA” jumper strips are inserted. � Make sure that the “POWER SEL” jumper is in the “USB” position. � Connect the host PC to the board through the provided USB cable.
