Hi,

I am using STM8S103 where I noticed that its UART BAUD rate is not supported for 1200bps at BRR1=41H and BRR2=36H (as per ref. manual ) tested at 16Mhz internal with pre-scaler at 1 and at 16Mhz external.

Whereas it is working OK with all bps setting above then 9600BPS.

Can any body FIX this issue ?
