The module' s function is to verify the implementation and the PC for basic serial communication functions. Installed on a PC requires a serial port debugging tool to verify the functionality of the program. Program implements a send and receive a 10 bit (that is, no parity bit) serial controller, 10 bit is a start bit, 8 data bits, 1 stop bit. Serial port baud law by the parameters defined in the program div_par decision to change the parameters of the corresponding baud rate can be achieved. The program is currently set div_par value 0x145, corresponding to the baud rate is 9600. 8 times the baud rate with a clock to send or receive every bit of the cycle time is divided into eight time slots so that the communication synchronization.
