in MC9S12XEP100datasheep I found a question , the "table A-25 IPLL Characteristics" At the bottom  fosc = 4MHz configured as fBUS = 50MHz, REFDIV = 01,REFFRQ = 01; but I found at the table "11-2.reference clock frequency selection" if REFDIV = 01 , and the  fREF = 4/(1+1)=2M; Shouldn't REFFRQ be equal to 0 ?


Thank you.

Have a great day
