Hello All,

I am using USART3 in Half duplex mode for 1 wire protocol. The reset pulse of the one wire protocol has to be sent at 9600 and data exchnage at 115200.
The problem I am facing here is BRR register doesnt get updated with baud rates.
HSE_VALUE is 8Mhz
 SYSCLK(Hz)                             |64000000
APB1 prescalar is  16
I am not getting the proper baud rate and hence i get just 0 from 1 wire slave.
Could anyone pls help in resolving this issue .

Thanks
