the HC11 line of microcontrrollers is now all but obsolete. Mu ch of the line of 
processors have been obsoleted. The replacement/upgrade was the HC12 is now 
becoming legacy products now. The preferred newer line is the S12 line of 
processors. They are upward compatible to the HC11 with more stuff in them. 

If t eh HC12/S12 line had the U register then one could reassemble 6809 code 
into the HC12/S12 line of processors. Outside code that uses U register, 
everything else will reassemble rather easily.
