| 14 | help |
| 15 | System Control and Power Interface (SCPI) Message Protocol is |
| 16 | defined for the purpose of communication between the Application |
| 17 | Cores(AP) and the System Control Processor(SCP). The MHU peripheral |
| 18 | provides a mechanism for inter-processor communication between SCP |
| 19 | and AP. |
| 20 | |
| 21 | SCP controls most of the power managament on the Application |
| 22 | Processors. It offers control and management of: the core/cluster |
| 23 | power states, various power domain DVFS including the core/cluster, |
| 24 | certain system clocks configuration, thermal sensors and many |
| 25 | others. |
| 26 | |
| 27 | This protocol library provides interface for all the client drivers |
| 28 | making use of the features offered by the SCP. |

| 80 | You must also enable the appropriate drivers (serial, VGA, etc.) |
