The divisor latch registers are used to program the baud
rate divisor. This is a value between 1 and 65535 by which
the input clock is divided by in order to generate serial
baud rates. After a hardware reset, the baud rate used by
the transmitter and receiver is given by:
Where divisor is given by DLL + ( 256 x DLM ). More
flexible baud rate generation options are also available.
See section 14 for full details.

The scratch pad register does not affect operation of the
rest of the UART in any way and can be used for
temporary data storage. The register may also be used to
define an offset value to access the registers in the
Indexed Control Register set. For more information on
Indexed Control registers see Table 7 and section 15.
