Setting the Baud Rate

You can set the baud rate using DIP switches on the development boards. The DIP switch value must match with the speed value set in the Tera Term software. You need to press pushbutton SW5 (rst_n) after each time you change the baud rate.

Table 2. Baud Rate and DIP Switch Settings for Titanium Ti60 F225 Development BoardThe baud_rate[2] is connected to GPIOR_N_13 and fixed to 0 in the design because there are only two DIP switches available on the Titanium Ti60 F225 Development Board. As a result, you can only select 4 baud rates in this example.

Baud Rate	DIP Switch Settings
	SW2.1 (baud_rate[1])	SW2.2 (baud_rate[0])
115200	0	0
57600	0	1
38400	1	0
19200	1	1
