Hello Grzegorz Konopko,
I understand your question. however CW10.x for HCS08 doesn't have feature to print to console, it is not possible since there is NO "standard output" to console in CW10.x for HCS08.
so User has to implement their own "pseudo" prinf() function, i.e. to format the output in memory and then print out through SCI.
