18.1 Overview

The Oscillators Controller (OSCCTRL) provides a user interface to the XOSC48, RC DFLL48M, and one PLL 12.7 MHz to 200 MHz or up to 1.6 GHz for fractional divider module use. 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.
