CC1310 RTC

The RTC is used by TI-RTOS as the time base for the ti.sysbios.Clock module. It continues to run even when the processor is in standby mode and will wake the processor whenever a Clock object times out.

Clock objects are used to implement the timeouts for BIOS APIs such as Task_sleep(), Semaphore_pend(), Event_pend(), etc. They are also used internally by various TI-RTOS driver functions when a timeout is required.

The RTC is also used as the timebase for the ti.sysbios.hal.Seconds module which can be used to provide time-of-day information to your application.
