Serial_Disable - Conrad C-Control Pro Mega Series Manual

177 C-Control Pro Mega Series
divider = (14745600 / baudrate / 16 ) -1
Example: 15 = (14745600 / 57600 / 16 ) -1
DoubleClock Mode
If the High-Bit of the divider is set, the DoubleClock Mode is enabled. In this mode the divider value
must be doubled. E.g. for 57600 baud a divider value of 0x0f (decimal 15) or 0x801e can be used.
For the MIDI baudrate (31250 baud) a divider of (14745600 / 31250 / 16 ) -1 = 28.49 had to be used.
If DoubleClock is enabled, the divider value can be specified more accurate: 0x8039
