<control register>
- Is a single byte character (see Figure 6-1, Control
Register Map) required to specify the baud rates. If the lower 4 bits of
the baud rate is equal to zero (0), the <opt baud low><opt baud high>
characters give you a rate based on the following:
<opt baud low>=<system frequency/rate/2-100-<opt baud high>*256
<opt baud high>=INT((system frequency/rate/2-100)/256
