This section describes the functionality and design of the always-on, real-time clock (AON_RTC) for the CC13x2 and CC26x2 device platform. The AON_RTC implements a second and subsecond counter with support for software-compensation of ppm-offsets, with three match register and one compare register.
A special mechanism is in place to support power down of the MCU domain while the AON_RTC continues to operate. The AON_RTC is powered in all power modes except for the deepest power-down mode, known as shutdown.
