Void SCIx_Select_Baudrate (SCI_Baudrate_Type
Baudrate_Prescaler)
Selects Transmit/Receive baudrate for SCI without ex-
tended baudrate prescaler. You have to define all the
prescaler parameters corresponding to the desired
baudrate speed. You have to pass the three input param-
eters by logically ORing them to select the baudrate.
