Direct Drive (PLL Bypass Operation)
During PLL bypass operation, the system clock has the same frequency as the external
clock source.
PLL Mode
The CPU clock is derived from the oscillator clock, divided by the NR factor (PDIV),
multiplied by the NF factor (NDIV), and divided by the OD factor (KDIV). PLL output must
