    Hi Durga. You can access all the registers present in your controller in the corresponding header file. In your case it is tm4c123gh6zrb.h. These headers are present in TivaWare/inc folder. Regards, Shashank

    Don't find either, earlier response to clearly provide your requested, "read the register value."  Thus suggest:

    ulTemp1 = HWREG(PWM0_BASE + PWM_O_ENABLE);

    ulTemp2 = HWREG(ADC0_BASE + ADC_O_SSFIFO0);

    ulTemp1 will hold the value w/in Register PWM_O_ENABLE while ulTemp2 receives, ADC_O_SSFIFO0.

    Usually these Registers are listed w/in several .h files w/in your project.  A search of the .h file of your targeted peripheral and even a broader IDE based, "search w/in project files" will provide detail on these & similarly related MCU Registers.
