The AON domain contains circuitry that is always enabled, except for the shutdown mode (where the digital supply is off). This domain includes the following:
Real-Time Clock (RTC): The RTC can be used to wake the CC13x4x10 and CC26x4x10 device platform from any state where it is active.
The RTC contains three match registers and one compare register. With software support, the RTC can be used for clock and calendar operation. The RTC is clocked from the 32 kHz RC oscillator or the 32 kHz crystal oscillator.
Battery Monitor and Temperature Sensor (BATMON): The battery monitor and temperature sensors are accessible by software. BATMON provides continuous monitoring of battery state as well as coarse temperature.
Always On Watchdog Timer (AON_WDT): AON_WDT is used to regain control when the system has failed due to a software error or to the failure of an external device to respond in the expected way specifically during standby
