Assume the bus clock is 50 MHz. Write a C program that initializes the serial port to communicate at Z bits/sec, 8-bit data, 1 start bit, and 1 stop bit. For students in Lab Sections 1 and 2, use UART 3 and Z is 19600 bits/sec. For Students in Lab Sections 3 and 4, use UART 4 and Z is 15600 bits/sec. For students in Lab Sections 5 and 6, use UART 5 and Z is 6600 bits/sec.
