0278 Only valid for DCDC regulators. Setup 1 for PWM mode, 0
0279 for AUTO (PWM/PFM) mode. The DCDC regulators work in a
0280 mixed PWM/PFM mode, using PFM under light loads and
0281 switching to PWM for heavier loads. Forcing PWM mode
0282 trades efficiency under light loads for lower output
0283 noise. This probably makes sense for HiFi audio related
0284 applications that aren't battery constrained.
