    I'm trying to get the Maximum Baud Rate possible from the SCI -

    According to the Data Sheet its 500k.

    Look at my configuration and tell me if it's gooing to work -

    The configuration is for 1M Baud Rate with 16MHz CPU osc.

    SCIBRR = 0x00

    SCIEPRP = 0x01

    SCIETPR = 0x01

    As you can see I'm using the extended mode of the SCI.

    What do you say ?

    500K is the maximum the sci may be set, this is stated in the datasheet for the device.

    On the newer devices it is possible to reach the maximum baud rate by just using the conventional Baud Register - TR & RR=1, PR=1.

    The older devices have to use the extended Baud Register. (ST removed the /2 from the BRR frequency).
