UNREGEUDD er POWER POWER SUPPLY MC68HC908JK DEMO BOARD The IDB HC08JK Demo Board Supported Devices The IDB HCO08JK Evaluation Board supports the following devices MC68HC908JK1 MC68HC908JK3 And any future MC68HC908JK family pin to pin compatible device Recommended Reading Motorola MCU CD ROM or individual datasheet Motorola CPU08 Central Processor Unit Reference Manual inDART HCO08 User s Manual Sof lec MICROSYSTEMS Page 2 IDB HCO8JK User s Manual 2 Getting Started Overview The IDB HCO8JK Evaluation Board may be used as a standalone application or with a MONO08 based emulator programmer host mode Standalone Mode The IDB HC08JK Evaluation Board comes with the microcontroller pre programmed with a sample application When working in standalone mode the sample application configures the A D peripheral to convert on the A D channel connected to the potentiometer and displays the results on the LEDs In order for the IDB HCO8JK Evaluation Board to work in standalone mode the MONOS connector s pins must be jumpered as show below factory setting J2 1 15 16 MONDOS Connector Jumpered for Standalone Mode Operation Additionally you must verify that the board s other jumpers are set correctly Make sure that both the OSC1
3. J6 and OSC2 J7 jumpers select the INT position This is needed to enable the on board 16 MHz crystal oscillator Make sure that all of the LED ENABLE jumpers J10 and the POTENTIOMETER ENABLE jumper J9 are inserted Make sure that the pre programmed sample device is in the appropriate socket on the board Finally power up the board The IDB HCO8JK Evaluation Board can be powered either via the UNREG VDD connector J3 or the REG VDD connector J4 The UNREG VDD connector accepts 9 12 V DC 200 mA wall plug in power supply with a 2 1 mm pin and sleeve plug with positive in the center and sleeve as ground When powering the board through this connector make sure the VDD SOURCE connector J11 selects the UNREG Position The UNREG VDD voltage is internally regulated to 5 V DC The REG VDD connector accepts 5 V DC max When powering the board through this connector make sure the VDD SOURCE connector J11 selects the REG Position The REG VDD voltage directly powers the microcontroller and the rest of the board Sof lec MICROSYSTEMS Page 3 IDB HCO8JK User s Manual Upon powering up the board the green POWER LED turns on By rotating the potentiometer you affect the results of the A D conversion and the value of each conversion is displayed in a linear bar fashion on the LEDs Host Mode The IDB HCO8JK Evaluation Board can
4. be used in conjunction with a MONDOS8 based emulator programmer such a SofTec Microsystems inDART HCOS8 In Circuit Debugger Programmer or a Motorola development tool If you use the evaluation board with SofTec Microsystems inDART HC08 a sample application similar to that described in the previous section can be executed in Host mode where the program execution is controlled by the host PC You can use the PC additionally to debug the application by for example execute the program step by step and watching how the microcontroller registers vary by using the Metrowerks CodeWarrior HC08 IDE provided with inDART HCO8 The example is available both in Assembly and in C language Please refer to the inDART HCO8 user s manual for a step by step tutorial In order to work with an emulator programmer the jumpers in the MONO8 connector must be removed and the MONOS cable of the emulator programmer must be connected to the evaluation board s MONOS connector J1 connector taking care of the proper polarity The J2 connector is not used in this mode 3 MONO8 Connections J1 Connector Pin Name Description RST_OUT Reset signal to target system GND or open drain output reflecting the state of the MCU RST and RST_IN signals GND System ground RST_IN Reset signal from target system GND to Vpp input to control the state of the MCU RST and RST_OUT signals RST MCU reset held at Vpr Vpp depending on the target mi
