Baud Rate Settings
A baud rate is set by software by dividing the clock input (1.8432MHz). The baud rate in terms of
hardware can be set to a maximum of 115,200 bps for SERIAL A, B. The baud rates available in
practice depend on the operating environment (cable, software, etc.). The table below lists typical baud
rates and their respective values to be written to the divisor latch register (LSB, MSB).
