Hi. Looking in the data sheet for the 16F628, I can see no specified data for 9600 baud below 1Mhz Xtal freq. Have anyone used the UART at 9600 baud at lower speeds then 1Mhz ? I'm looking at a (very) lowpower application, and one (or "the") way to get low power is low speed, right ? A couple of 100's kHz would probably be just fine. It will just be a/some PIC talking on a serial line and on non-volatile memory, probably FRAM due to the write speed. The "other side" is fixed to 9600 baud.
