2.1.2.1 CC13x0 and CC26x0 Operation Modes

The Sensor Controller is in active mode when running task code and in standby mode otherwise. The Sensor Controller firmware framework, which is integrated in the generated driver, autonomously handles the transitions into and out of standby mode.

All peripheral modules are available in active mode, unless they are used by the System CPU. A small number of peripherals can be used in standby mode to trigger wakeup of the Sensor Controller.

Table 2-2 lists the Sensor Controller/AUX domain clock source and frequency for the different modes of operation.

ActiveSensor Controller clock24 MHz (SCLK_HF / 2)24 MHz (SCLK_HF / 2)
AUX bus clock24 MHz (SCLK_HF / 2)24 MHz (SCLK_HF / 2)
Standby with event triggerSensor Controller clock24 MHz (SCLK_HF / 2)32 kHz (SCLK_LF)
AUX bus clock24 MHz (SCLK_HF / 2)32 kHz (SCLK_LF)
