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.
