The Oscillator Control register (OSCCTL) enables or disables the various oscillator
circuits, enables/disables the failure detection/recovery circuitry, actively powers down
the flash, and selects the primary oscillator, which becomes the system clock.
The Oscillator Control register must be unlocked before writing. Writing the two-step
sequence
The register locks after completion of a register write to the OSCCTL.
