28.6.1 Principle of Operation

XOSC, DFLL48M, and FDPLL200M are configured via 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. 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.
