225 * OFF: The regulator is switched off and the output voltage is discharged.
226 * PFM: In this mode, the regulator is always in PFM mode, which is useful
227 * at light loads for optimized efficiency.
228 * PWM: In this mode, the regulator is always in PWM mode operation
229 * regardless of load conditions.
230 * APS: In this mode, the regulator moves automatically between pulse
231 * skipping mode and PWM mode depending on load conditions.
