18.6.1 Principles of Operation

XOSC, DFLL48M, and PLL 1.6G are configured through the OSCCTRL control registers. Through this interface, the 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.
