from a brief study, this 12bit DAC, and DAC module in general, is only on
this mcf45441x family. There are some ColdFire with ADC only, as those
mcf5249/53/82. 
The mcf51mm/ag/je are the opnly to have a 5bit dacs, but these are mcus.
So, if i don't miss any existing model, the name may be correct,
unless we want rename it to a more generic mcf_dac.
