PLL Mode
The system clock is derived from the oscillator clock, multiplied by the N factor, and
divided by the P and K factors. Both VCO bypass and PLL bypass must be inactive for
this PLL mode. The PLL mode is used during normal system operation.
System Frequency Selection
For the XC886/888, the value of P is fixed to 1. In order to obtain the required fsys, the
value of N and K can be selected by bits NDIV and KDIV respectively for different
oscillator inputs. The output frequency must always be configured for 96 MHz.
