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. 188c2ecf20Sopenharmony_ci 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. 238c2ecf20Sopenharmony_ci 248c2ecf20Sopenharmony_ciproperties: 258c2ecf20Sopenharmony_ci compatible: 268c2ecf20Sopenharmony_ci const: fsl,imx7ulp-smc1 278c2ecf20Sopenharmony_ci 288c2ecf20Sopenharmony_ci reg: 298c2ecf20Sopenharmony_ci maxItems: 1 308c2ecf20Sopenharmony_ci 318c2ecf20Sopenharmony_cirequired: 328c2ecf20Sopenharmony_ci - compatible 338c2ecf20Sopenharmony_ci - reg 348c2ecf20Sopenharmony_ci 358c2ecf20Sopenharmony_ciadditionalProperties: false 368c2ecf20Sopenharmony_ci 378c2ecf20Sopenharmony_ciexamples: 388c2ecf20Sopenharmony_ci - | 398c2ecf20Sopenharmony_ci smc1@40410000 { 408c2ecf20Sopenharmony_ci compatible = "fsl,imx7ulp-smc1"; 418c2ecf20Sopenharmony_ci reg = <0x40410000 0x1000>; 428c2ecf20Sopenharmony_ci }; 43
