Num C
Clock Monitor Failure is asserted if the frequency of the incoming clock signal is below the Assert
Frequency f
A.5.3 Phase Locked Loop
The oscillator provides the reference clock for the PLL. The PLL´s Voltage Controlled Oscillator (VCO)
is also the system clock source in self clock mode.
A.5.3.1 XFC Component Selection
This section describes the selection of the XFC components to achieve a good filter characteristics.

NOTES:
1. Depending on the crystal a damping series resistor might be necessary
2. f
3. Maximum value is for extreme cases using high Q, low frequency crystals
4. XCLKS =0 during reset
