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:
- The RTC can be used to wake the CC13x2x7 and
CC26x2x7 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.
- The battery monitor and temperature sensors are accessible by software. The battery monitor and temperature sensors provide continuous monitoring of battery state as well as coarse temperature.
