QUESTIONS Assume all registers are reset to 0 before initialization Preserve unused register bits (unless you explain why they don't need to be preserved, or the - code provided does not preserve them). r Numbers used in code must be in hex, binary or decimal format. Do not use M rmat values. Pay attention to the format of numbers given in code. 1. 120 pts] UART a) Complete the following lines of code to initialize the GPIO module for UART4 for both transmit and receive operation. (10 pts) void UART_init (void) SYSCTI_ RCGCGPIO_R I GPIO PORTC DEN R I GPIO PORTC_DIR R GPIO PORTC AFSEL R GPIO PORTC PCTL R // Other initialization code not shown b) Write a single line of code to set the frame format for UART4 to 7 data bits, 1 stop bit, even parity, and FIFO mode. (5 pts) c) Assuming interrupts are enabled, write a single line of code for the interrupt handler to check whether an interrupt occurred due to a character being received.
