12.1 Divisor Latch Registers ‘DLL & DLM’
The divisor latch registers are used to program the baud

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.
