NOTES
• LSB = 0x93 (rounded)
• MSB = 0x00
• Intended Baud Rate: 13,500 baud
• Results from the formula are rounded down to the nearest whole number (i.e 73.07
• 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.
• The actual baud rate must be within 3% of the intended baud rate for the device to
