Default values for the PLLDIV0, PLLDIV1, PLLDIV2, and PLLDIV3 bits are /1 (0 0000), /1 (0 0000), /2 (0 0001), and /2 (0 0001), respectively.
CAUTION:
D1 and D2 should never be disabled. D3 should only be disabled if ECLKIN is used.

Note that SYSCLK2
must
run at half the rate of SYSCLK1. Therefore, the divider ratio of D2 must be two times slower than D1. For example,
if D1 is set to /2, then D2
must
be set to /4.
