NOTES
?
Results from the formula are rounded down to the nearest whole number (i.e 73.07
= 73).
?
This formula becomes less acurate as baud rates increase, due to rounding.
?
Place the speed result backwards into the formula to receive
the actual baud rate.CrystalSpeed

?
The actual baud rate must be within 3% of the intended baud rate for the device to
communicate.
