EMUL instruction cycle ?error?

I have noticed that the instruction cycle count in the disassembly listing shows that the EMUL instruction uses one clock cycle, 0000  13  [1]  EMUL, however the instruction matrix for the 9S12 says EMUL uses 3 clocks.  Is there a file that CodeWarrior uses that can be corrected so that the listing will be correct?  Or is it true that the EMUL instruction does such a fast multiply?\
