Hi Alexandros,
Your project is using Device Initialization feature.
This feature is not generated code as Processor Expert but only intialization of the perhipheral which is defined in the MCUinit.c and .h files
Processor Expert includes some function to manage the peripheral.
Some information extracted of help:

To access this help, please click on Help Tab on Device Initialization Component.
If you need more generated code, you need to select Processor Expert instead of Device Initialization.
Another option is to not use these features too.
There are examples in the folder \CodeWarrior for Microcontrollers V6.3\(CodeWarrior_Examples)\RS08\Assembly Examples\
Have a great day,
Pascal
