18.6.1 Principle of Operation

XOSC, DFLL48M, and FDPLL200Mn are configured through the OSCCTRL control registers. Through this interface, these oscillators are enabled, disabled, or have their calibration values updated.

The Status register gathers different status signals coming from the oscillators controlled by the OSCCTRL register. The status signals can be used to generate system interrupts, and in some cases wake up the system from Sleep mode, provided the corresponding interrupt is enabled.
