15.6.1 Principle of Operation

The XOSC32K, OSC32K, and OSCULP32K are configured through the OSC32KCTRL 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 of the OSC32KCTRL Control register. 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.
