restrictions:

- cclk must be i*hclk
|

- i must not be 24 or 32
|
||||
- hclk = mclk or hclk = 2*mclk
|

- mclk = k*pclk
|
||||
|

so:
|
||||
- pclk is set
|

- mclk = k*pclk
|

- hclk = l*mclk = l*k*pclk; l = 1 or 2
|

- cclk = i*hclk = i*l*k*pclk; i != 24 or 32

|

In the code:
|

m = 42
|

n = 2
|

no = 1
|

So clkout = 12M * 21 = 252M; this is the pll clock frequency.
