Please correct me if I am wrong, according to the PM, when the register 
value of OD is 0, 1, 2, 3, the value corresponding participating PL 
frequency calculation is 1, 2, 4, 8. Therefore, change

m = (rate / MHZ) * ++od * n / (parent_rate / MHZ); to m = (rate / MHZ) * (2 ^ od++) * n / (parent_rate / MHZ); seems to be more appropriate, it can avoid 3, 5, 6, and 7 that should not exist.

If we change the above formula, we also need to change this to *pod = 2 
^ od;


Thanks and best regards!
