LPC11xx docs state that in order to switch to a new clock source, the source must be running. How do I know that watchdog oscillator is running? I couldn't find a reference to any osc startup time or status flags in LPC11xx docs, but maybe I am not smart enough.
In my project I have a problem with switching WDT to WD OSC which I believe is not running and probably the switch does not occur - WDT still runs on IRC osc.
