Baud-law decided by div_par parameters defined in the program, you can change the parameters to achieve the appropriate baud rate. Value of the program is currently set div_par Is 0x145, the corresponding baud rate is 9600. An 8 times the baud rate clock to send or receive every bit of the time period is divided into eight time slots so that the pass Letter synchronization. (2016-03-09, VHDL, 334KB, 下载2次)
