The module s function is to verify the implementation and the basic PC, the serial communication function. Need PC,
Install a serial debugging tools to verify the functionality of the program.
Program implements a receive a 10 bit (ie no parity bit) of the serial controllers, 10
bit is a start bit, 8 data bits, 1 stop bit.
Serial Porter law defined by the program parameters div_par decision can change the parameters of the corresponding
Baud rate. Program the value of the current set div_par
Is 0x104, the corresponding baud rate is 9600. 8 times the baud rate with a clock will be sent or received per
A bit of the cycle time is divided into eight time slots in order to pass
Information synchronization.
The basic process is the work program, press a button SW0, the controller s serial port to the PC
