18.1 Overview

The Oscillators Controller (OSCCTRL) provides a user interface to the XOSC, RC DFLL48M, and two PLL 12.7 MHz to 300 MHz or up to 1.6 GHz for fractional divider module use. Through the interface registers, users can 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 through the INTENSET, INTENCLR, and INTFLAG registers.
