18.1 Overview

The Oscillators Controller (OSCCTRL) provides a user interface to the XOSCn, DFLL48M, and two FDPLL200Mn. Another clock controller (OSC32KCTRL) provides a user interface to 32.768 kHz oscillators.

Through the interface registers, it is possible to enable, disable, calibrate, and monitor the oscillators.

The status of all oscillators are collected in the Status register (STATUS). They can additionally trigger interrupts upon status changes via the INTENSET, INTENCLR, and INTFLAG registers.
