291 Only valid for DCDC regulators. Setup 1 for PWM mode, 0
292 for AUTO (PWM/PFM) mode. The DCDC regulators work in a
293 mixed PWM/PFM mode, using PFM under light loads and
294 switching to PWM for heavier loads. Forcing PWM mode
295 trades efficiency under light loads for lower output
296 noise. This probably makes sense for HiFi audio related
297 applications that aren't battery constrained.
