13.9.1 Overview
The Oscillators Controller (OSCCTRL) provides a user interface to the XOSC, OSC16M, DFLL48M, and FDPLL96M.
Through the interface registers, it is possible to enable, disable, calibrate, and monitor the OSCCTRL sub-peripherals.
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.
