The lowest system clock frequency results from selecting the maximum value for the
divider factor K1:

Phase Locked Loop (PLL)
When PLL operation is selected (SYSCON0.CLKSEL = 10
the on-chip phase locked loop is enabled and provides the system clock. The PLL
multiplies the input frequency by the factor F (
F is calculated from the input divider P (= PDIV+1), the multiplication factor N (=
NDIV+1), and the output divider K2 (= K2DIV+1):
(F = N / (P × K2)).
The input clock can be derived either from an external source at XTAL1 or from the on-
chip clock source.
The PLL circuit synchronizes the system clock to the input clock. This synchronization is
performed smoothly so that the system clock frequency does not change abruptly.
Adjustment to the input clock continuously changes the frequency of
locked to
of individual TCSs.
