PLLConfig—PLL Configuration Register
Bits 7, 6: PLLFactor[n]
The PLLFactor[n] bits allow programming the PLL multiplication factors. The input and output frequencies of the PLL
have to be limited to the ranges shown in Table 7. Enable the PLL through CLKSource[2].
Bits 5–0: PreDiv[n]
The PreDiv[n] bits allow programming the divisor of the PLL’s predivider. The divisor must be chosen so that the output
frequency of the predivider, which equals the PLL’s input frequency, is limited to the ranges shown in Table 4. The
input frequency of XIN, is fCLK:
fPLLIN = fCLK/PreDiv
See Figure 17. PreDiv is an integer that must be in the range of 1 to 63.
