Hello, how to read the RTC counter value in TM4C123G using the timer driver library since there is no API referring to it ?

Thank you

    Hello Ahmed

    To us the Timer in RTC mode, you would need to provide a 32KHz clock on the CCP pin. The next thing you would need to do is to configure the timer using TimerConfigure API call with the mode set as TIMER_CFG_RTC in full width mode.

    You can check the timer.h for the API for setting the Timer Match in RTC.
