22.1 Overview

The 32KHz Oscillators Controller (OSC32KCTRL) provides a user interface to the 32.768kHz oscillators: XOSC32K, OSC32K and OSCULP32K.

The OSC32KCTRL sub-peripherals can be enabled, disabled, calibrated, and monitored through interface registers.

All sub-peripheral statuses are collected in the Status register (STATUS). They can additionally trigger interrupts upon status changes via the INTENSET, INTENCLR, and INTFLAG registers.
