| description: > |
| 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. |
