Hi Tezkaplipoka,

Have a look at the Motorola web site :

h**p://e-w*w.motorola.com/webapp/sps/site/prod_summary.jsp?code=MPC860&nodeId=03DnXMztdcv4N0DKCb

Scroll down the page. They have a tool named MCUINIT 3.1 that helps you through the initialisation of some internal peripherals like UPM. You can download it (warning total download > 45Mo).
