This clock is always on (cannot be switched off for system safety reasons)
In the peripheral subsystem parts of the timers, watchdog timer, SPI and UART have their own clock
source. See
The clock should remain activated when system wake-up on timer or UART is required.
In the Power, Clock and Reset control SubSystem (PCRSS) parts of the CGU, RGU, and PMU have their
own clock source. See
