+This directory contains the support code for the EK-TM4C123GXL board
+(TivaC LauchPad).
+
+The sub-directories contain code that is specific to the particular
+ARM toolchains, such as ARM (MDK-ARM), GCC, and IAR.
+
+
+CMSIS-Compliant Device Files
+============================
+The code also includes the CMSIS-compliant interface to the TM4C123GH6PM
+MCU files:
+
+TM4C123GH6PM.h
+system_TM4C123GH6PM.h
+system_TM4C123GH6PM.c
+arm\startup_TM4C123GH6PM.s
+gcc\startup_TM4C123GH6PM.c
+iar\startup_TM4C123GH6PM.s
+
+
+Adjusting the CPU Clock Speed
+-----------------------------
+The current setting is to run at 50MHz from PLL, but the CPU clock speed
+can be modified by editing the file system_TM4C123GH6PM.c.
