Motorola at one time was shipping well over ten million HC11E9 each year. 
The flavor of the HC11 that I was using on a project was the third or fourth 
popular flavor, the HC11P8. At one time we were using almost 2 million per 
year. At one time there were about 20 or 30 flavors of HC11. The HC11 is 
being replaced by the HC12 in automobile use. The HC12 is upward source 
compatible and has some of the same instructions that the 6809 has. Almost 
like taking the best of the 6809 and the HC11 and combining them. They just 
needed to add one more register, U.
