After the values for DIV and T3FD are calculated, the actual
baud rate can be calculated using the following formula:
For example, to obtain a baud rate of 115,200 while operating at
16.78 MHz,
Therefore, the actual baud rate is 114,912 bits/sec.
DIV = log(11,059,200/(32 × 115,200))/log(2) = 1.58 = 1
T3FD = (2 × 11,059,200)/(21 × 115,200) − 64 = 32 = 20H
