Hi,
Since the commit 20104a6 it is not possible to set the UART baudrate to 300 anymore. We're now using the fractional mode of the SERCOM and sercom->USART.BAUD.FRAC.BAUD
can only hold 13 bits while at 300 baud you want to write 10000
. It doesn't fit.
To be honest, I don't even know how accurate the 300 baud used to be before this change, but we only use it to emulate sending a break. And that is not possible anymore.
Should we perhaps switch to the non-fractional mode if we detect that there is an overflow of the 13 bits?
