C) Answer the following questions: (5 marks) Write the needed code to clear TXIF and RCIF Flags. Draw a waveform of (OXOF), received at RX pin, use NRZ format. Calculate the value of SPBRG Register, if the external clock 12MHz, and we want to transmit in 14400 Buad, calculate for low BRGH and determine the error for calculation?
