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

| Allowed Buck regulator operating modes allowed. Valid values below. |
| 0 - Normal mode with automatic power saving, reducing the switching |
| frequency when light load conditions are detected |
| 1 - Forced Continuous Conduction mode (FCCM) for improved voltage |
| regulation accuracy with constant switching frequency but lower |
| regulator efficiency |
| 2 - Forced Low Power mode for improved regulator efficiency, used |
| when no heavy load is expected, does not limit the maximum out |
| current but unless only a light load is applied, there will be |
| regulation accuracy and efficiency losses. |
| 3 - Forced Ultra Low Power mode for ultra low load, this greatly |
| reduces the maximum output power, makes the regulator to be |
| efficient only for ultra light load, and greatly reduces the |
| quiescent current (Iq) of the buck. |
