Description
Reserved.
Set these bits to 001 at all times for proper operation.
Setting this bit enables a soft transition between filter settings to minimize output transients.
All four parameters of each filter are linearly transitioned to the new value.
[1:0]
Transition speed
R/W
These bits set the transition speed from one filter to another. The filter changes in 32 steps;
each step is applied at the multiple of switching cycles (t SW ) specified by these bits.

Description
If this bit is set to 1, the soft start flag is ignored by PGOOD1. This bit must be set to 0 to enable
proper PGOOD1 debounce timing after the end of the soft start ramp.
