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.
