HI:
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
hi,
the easiest answer I can provide you is the answer I sent a few days ago and you will not be able to think about calculation complexity.
