The Oscillators Controller (OSCCTRL) provides a user interface to the XOSC, OSC16M, DFLLULP and FDPLL96M. Through the interface registers, users can enable, disable, calibrate, and monitor the OSCCTRL oscillators. All oscillators statuses are collected in the Status (STATUS) register. They can additionally trigger interrupts upon status changes through the INTENSET, INTENCLR, and INTFLAG registers.
