The flexibility of the power management of the CC13x2x7 and CC26x2x7 device platform allows many different configurations to achieve a low-power application. This section describes the power modes, as defined by TI-RTOS, which cover a range of power-saving modes (from low-power savings with fast-cycling time to high-power savings with long-cycling time).
Table 8-5 provides an overview of the power modes defined in TI-RTOS.
