Active Mode

In active mode, the Cortex®-M3 either executes code or waits through a WFI instruction for interrupts. System resources are available in active mode. The CPU power domain, peripherals, and radio may be active. Because the resources on CC26x0 and CC13x0 devices are available to the application in this mode, the current consumption depends on which modules are used.

If the Cortex-M3 executed a WFI instruction, it can wake up from any enabled interrupt source. The difference between active and idle mode (see Section 3.2) is that in active mode the CPU power domain remains on, ensuring a quick wake up. The wake-up time from idle mode is longer because the CPU power domain must be turned on again.
