19.1 Overview

The Oscillators Controller (OSCCTRL) provides a user interface to the XOSC and oscillator used during start-up operation (DFLL). Each oscillator is controlled by dedicated registers in the OSCCTRL. Through this interface, the oscillators are enabled, disabled, or have their configuration 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. Generated events can be used by the system to trigger actions on other peripherals
