21.6.1 Principle of Operation

XOSC, OSC16M, DFLL48M, and FDPLL96M are configured via OSCCTRL control registers. Through this interface, the sub-peripherals are enabled, disabled, or have their calibration values updated.

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