 13  The MT6363 SPMI PMIC provides 10 BUCK and 25 LDO (Low DropOut) regulators
 14  and can optionally provide overcurrent warnings with one ocp interrupt
 15  for each voltage regulator.

 85            0 - Normal mode with automatic power saving, reducing the switching
 86                frequency when light load conditions are detected
 87            1 - Forced Continuous Conduction mode (FCCM) for improved voltage
 88                regulation accuracy with constant switching frequency but lower
 89                regulator efficiency
 90            2 - Forced Low Power mode for improved regulator efficiency, used
 91                when no heavy load is expected, does not limit the maximum out
 92                current but unless only a light load is applied, there will be
 93                regulation accuracy and efficiency losses.
 94            3 - Forced Ultra Low Power mode for ultra low load, this greatly
 95                reduces the maximum output power, makes the regulator to be
 96                efficient only for ultra light load, and greatly reduces the
 97                quiescent current (Iq) of the buck.
