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