138c2ecf20Sopenharmony_ci  The Multi-System Mode Controller (MSMC) is responsible for sequencing
148c2ecf20Sopenharmony_ci  the MCU into and out of all stop and run power modes. Specifically, it
158c2ecf20Sopenharmony_ci  monitors events to trigger transitions between power modes while
168c2ecf20Sopenharmony_ci  controlling the power, clocks, and memories of the MCU to achieve the
178c2ecf20Sopenharmony_ci  power consumption and functionality of that mode.

198c2ecf20Sopenharmony_ci  The WFI or WFE instruction is used to invoke a Sleep, Deep Sleep or
208c2ecf20Sopenharmony_ci  Standby modes for either Cortex family. Run, Wait, and Stop are the
218c2ecf20Sopenharmony_ci  common terms used for the primary operating modes of Kinetis
228c2ecf20Sopenharmony_ci  microcontrollers.
