3.10.4 Frequency selection
spikes or drops in the frequency of the output clock. The recommended way of changing
between divider settings is to power down the PLL, adjust the divider settings and then let
the PLL start up again.
The PLL frequency equations use the following parameters (also see
Table 54.
In this mode the post divider is enabled, giving a 50% duty cycle clock with the following
frequency relations:
To select the appropriate values for M and P, it is recommended to follow these steps:

1. Specify the input clock frequency Fclkin.
2. Calculate M to obtain the desired output frequency Fclkout with M = F
3. Find a value so that FCCO = 2 × P × F
4. Verify that all frequencies and divider values conform to the limits specified in
