PLL bypass mode:
• 0 = PLL is not in BYPASS mode
• 1 = PLL is in BYPASS mode
Output divider ratio bits
• 0h = ÷1. Divide frequency by 1
• 1h = ÷2. Divide frequency by 2
• 2h = ÷3. Divide frequency by 3
• 3h = ÷4. Divide frequency by 4
• 4h - Fh = ÷5 to ÷16. Divide frequency range: divide frequency by 5 to divide frequency by 80.

11.5.3.2 PLL Controller Divider Register (PLLDIV3, and PLLDIV4)
The PLL Controller Divider Registers (PLLDIV3 and PLLDIV4) are shown in Figure 11-10 and described in
Table 11-17. The default values of the RATIO field on a reset for PLLDIV3, and PLLDIV4 are different as
mentioned in the footnote of Figure 11-10.
