FlexRay PLL Parameters
This PLL unit is dedicated for usage with the FlexRay module. FlexRay operation
requires a high precision clock signal to fulfil the protocol timing requirements. If the
system clock is generated by use of a quartz it is mandatory to adjust the quartz
parameters in your target system. Please refer also to Chapter 4.7.3 for details.

4.7.2.2 Wakeup Clock
When wakeup operation is selected (SYSCON0.CLKSEL = 00_B), the system clock is
derived from the low-frequency wakeup clock source:
f_SYS = f_WU.
In this mode, a basic functionality can be maintained without requiring an external clock
source and while minimizing the power consumption.
