I'm trying to set the UART baud rate to 600 on a Nucleo F070RB board to communicate with the CS5490 chip. (https://www.cirrus.com/products/cs5490/)
I've only managed to go down to 732 baud rate. Anything below, it seems that the clock divider is not capable to produce (I think it overflows).
So, the question is, how can I achieve a 600 baud rate on this board?
