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.
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

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.
If this bit is set to 1, the CS1 fast OCP flag is ignored by PGOOD1.
If this bit is set to 1, the CS1 accurate OCP flag is ignored by PGOOD1.
If this bit is set to 1, the CS2 accurate OCP flag is ignored by PGOOD1.
If this bit is set to 1, the UVP flag is ignored by PGOOD1.
If this bit is set to 1, the local OVP flag is ignored by PGOOD1.
If this bit is set to 1, the load OVP flag is ignored by PGOOD1.
If this bit is set to 1, the OrFET flag is ignored by PGOOD1.
