| 13 | The Multi-System Mode Controller (MSMC) is responsible for sequencing |
| 14 | the MCU into and out of all stop and run power modes. Specifically, it |
| 15 | monitors events to trigger transitions between power modes while |
| 16 | controlling the power, clocks, and memories of the MCU to achieve the |
| 17 | power consumption and functionality of that mode. |
| 18 | |
| 19 | The WFI or WFE instruction is used to invoke a Sleep, Deep Sleep or |
| 20 | Standby modes for either Cortex family. Run, Wait, and Stop are the |
| 21 | common terms used for the primary operating modes of Kinetis |
| 22 | microcontrollers. |
