    Hi Cannie,

    Device attempts to lock to VCO first group divisors. If it cannot lock to one of the first group divisors then it will use group 2 divisors and attempts to lock.

    Please just set 0x2F[7:4] as noted in table 18 of the data sheet. For example, if 0x2F[7:4] = 0xC, device use divided by 8 and if there is no lock it will try to lock to divided by 1.
