HCS12X GETTING STARTED To get started quickly, please refer to the DEMO9S12XDT512 Quick Start Guide. This quick start will show the user how to connect the board to the PC, run a LED test program, install the correct version of CodeWarrior Development Studio, and load an Analog to Digital (ATD) test program using CodeWarrior. -
Page 7: Run Mode
RUN MODE Run mode allows user application to function when power is applied to the board. Use the following settings to configure the DEMO9S12XDT512 board for RUN Mode to get started quickly. 1. Connect auxiliary equipment to board as required by application. -

USB specification. Damage to the host PC USB hub or the target board may result. The communications speed over the USB bus is controlled by the USB_SPEED header. When shipped from the factory, the DEMO9S12XDT512 is configured for high-speed opera- tion. If the user encounters a communication failure, USB communication speed may be re- duced by setting this option jumper to Full. -
Page 10: Power
2 0 0 8 POWER The DEMO9S12XDT512 is designed to be powered through the USB-Multilink BDM during application development. A 2.0mm barrel connector has been applied to support stand-alone operation and to support LIN functionality. The board may also be powered through connector J1. -

Consult the MC9S12XDT512 reference manual for details LVR op- eration. TIMING Default timing configuration for the DEMO9S12XDT512 is a low-power, low-noise Pierce os- cillator. In this mode, oscillator swing is typically 1V . The Pierce oscillator input is supplied by a 4 MHz, fundamental frequency, crystal oscillator at location Y1. -

5.0V output will damage the MCU. COMMUNICATIONS The DEMO9S12XDT512 board provides two Enhanced Serial Communications Interface (ESCI) ports. SCI0 is applied to RS-232 serial communications (COM) on the target board. SCI1 is applied to LIN communications on the target board. RS-232 communications are sup- ported through a DB9 connector. -

Pins 1, 4, and 6 are connected together. LIN Communications The DEMO9S12XDT512 applies the MC33661D Local Interconnect Interface (LIN) physical layer (PHY) for use in developing automotive control applications. The MC33661D physical layer interface (PHY) supports LIN bus functionality for input voltages between +6V and +18V. -
