The RPU MPCore includes several power modes and power island states.
The CPUs include three power management states.
The following table lists the power management modes.
|Power Mode||CPU Clock||Power State||TCM Memory Retention||Exit to Run Mode Description|
|Standby||When idle||On||Yes||Pipeline restart|
|Shutdown||Inactive||Off||No||Pipeline restart restores registers and configuration from memory, invalidates caches, and reinitializes caches and TCMs|
The RPU MPCore includes several power islands as shown in the Power Diagram of the power chapter.
Note: All TCM power islands must be powered up to access any of the TCMs.
