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