PLLConfig—PLL Configuration Register
Table 4. PLLFactor[1:0] Selection Guide
Bits 7 and 6: PLLFactor[1:0]
The two PLLFactor[1:0] bits allow programming the PLL’s multiplication factor. The input and output frequencies of the
PLL have to be limited to the ranges shown in Table 4. Enable the PLL through CLKSource[2].
Bits 5–0: PreDiv[5:0]
The six PreDiv[5:0] bits allow programming the divisor of the PLL’s predivider. The divisor must be chosen such 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 f
