Using the tm4c123gh6pm.h header file, determine the names of the appropriate registers based on the functionality described below. Then use those names to configure Port F such that upper four pins (PF7 down to PF4) are output pins and the lower four pins (PF3 down to PFO) are input pins. Enable digital inputs for all input pins and then write an infinite while loop that reads the input pins and writes that same value on the output pins. Repeat the previous question using the TivaWare GPIO functions. (I encourage you to examine the example code shown on page 134 on the reference for some guidance in this.)
