Web4 Mar 2024 · For that first, substitute Tx/Rx baud and FPCLK values in equation 1. Now you have to calculate the division factor (USARTDIV), which is then stored into the USART_BRR register or baud rate generation register. If you solve equation 2, you will get the USARTDIV value as follows: USARTDIV = 16M/ (8 * 2 * 9600) = 104.17. http://www.iotword.com/8517.html
