Part a) Write a piece of code that configures the backchannel UART of the basic LaunchPad (G2553). You only need to divert the pins to UART functionality. The documents of the basic LaunchPad can be found on the main page of Webcourses. Part b) What is the oversampling scheme in UART?Part c) Is it possible to start with SMCLK = 1 MHz and configure 9600 baud with oversampling. Show how you obtained your answer. Part d) Is it possible to start with ACLK = 32 KHz and configure 9600 baud with oversampling. Show how you obtained your answer. Part e) What are the divider and modulator of the UART clock configuration? Where are these values found?
