    Hi,

      You can use HWREG() to read the register. You can use UARTprintf() to send to the terminal window. I will suggest you start with the TivaWare examples such as hello.c. The example can be found in <TivaWare_installation>/examples/boards/ek-tm4c123gxl/hell/hello.c. You can also find all the drivers in <TivaWare_installation>/driverlib. Pick any file you will find the HWREG() function to read and write to registers.
