T W R - S 0 8 L L / L H U S E R G U I D E A P R I L 2 7 , 2 0 1 0U S E R G U I D E6GETTING STARTEDTo get started quickly, please refer to the TWR-S08_QSG Quick Start Guide. This quick startwill illustrate connecting the board to a PC, installing the correct version of CodeWarriorDevelopment Studio, and running a simple LCD program.MEMORY MAPThe TWR-S08 is designed to support the complete line of MC9S08LL and MC9S08LH MCU’s.Refer to the associated target MCU Reference Manual (RM) for details on the target MCUmemory map.SOFTWARE DEVELOPMENTSoftware development requires the use of a compiler or an assembler supporting the HCS08instruction set and a host PC operating a debug interface. CodeWarrior Development Studiofor Microcontrollers is supplied with this board for application development and debug.DEVELOPMENT SUPPORTApplication development and debug for the target TWR-S08 board is supported through theOpen-Source Background Debug Mode (OSBDM) interface. The OSBDM is fully supported inCodeWarrior and provides direct, non-intrusive access to the target device internals. While inBDM mode, no internal resources are used. Code stepping and break-points are fullysupported.Connection between a host PC and the target device is provided via a mini-B, USB connector.The OSBDM is capable of providing power to the target board eliminating the need for externalpower. Please note that power supplied by the OSBDM is limited by the USB specification.When powered through the OSBDM, total current draw, including the OSBDM, TWR-S08board, and Tower System must remain less that 500mA. Otherwise, the USB bus will causethe host PC to disconnect the board. Damage to the host PC, target board, or Tower Systemmay result if this current limit is violated.NOTE:The OSBDM will not connect to the TWR-S08 board if the target MCU is inSTOP mode. Wake the target device with an external event then connect tothe target.
