Figure 7-3 shows that the MCU voltage domain contains the CPU system divided into multiple power domains. MCU_VD also includes always-on logic not encapsulated in a power domain, which is powered whenever the voltage regulator is on. The voltage regulator will be on and MCU_AON will be powered when the CC13x4x10 and CC26x4x10 device platform is not in shutdown or reset mode. Figure 7-3 shows this logic as MCU_AON.
