Serial Pre-Scaler and Baud Rate Divisor

  1. Mar 29, 2010 #1
    1. The problem statement, all variables and given/known data
    For the MC9S12DG256, determine the values for the serial prescaler and baud rate divisor for 115,200 bps.

    2. Relevant equations
    None that I am aware of...

    3. The attempt at a solution
    I know that baud is a number of pulses per second unrelated to the number of bits per second, which is given. The prescaler will extend the frequency available to the counter by dividing the bus clock frequency by a certain divisor. Possibly the 'baud rate' divisor?

    I know that this question is board/chip specific but any insight on the type of solutions or equation this problem would be similar or related to would be very much helpful.

    Thanks in advance
