2Open the Application

Software

Download and open the file up-down-

no-antipinch.mcpwith CodeWarrior

Development Studio for HCS12(X).

3Connect the

Board

Connect a 12 V automotive battery and

a brushed DC motor to the board. For

details, refer to the section titled, “Step-

By-Step Board Connection.”

4Download the Software to

the S12VR64 MCU Flash

Connect an HCS12(X) external debugger

to the computer and then connect the

debugger to J6. Follow the operating

system messages to install the debugger

drivers. Flash the application by pressing

the debug button on CodeWarrior.

Follow the debugger instructions to flash

the MCU.

INTRODUCTION SOFTWARE TOOLS INSTALLATION

The S12VR32 EVB features the S12VR32 microcontroller, an automotive 16-bit MCU

for applications based on motor control relays. The S12VR32 evaluation board

integrates an S12 CPU, a LIN physical interface, a 5 V regulator system to supply the

microcontroller and low-side drivers to control the relay.

This ultra-low-cost development platform also includes a Hall sensor interface, an

external 16 MHz oscillator, a switch button and an onboard OSBDM.
