This 8-bit read/write register has no effect on the UART. It is intended as a scratchpad
register for use by the programmer.
The UART contains a programmable Baud Rate Generator that is capable of taking the
UART_CLK input and dividing it by any divisor from 1 to (2
of the Baud Rate Generator is 16 times the baud rate. Two 8-bit latches store the
divisor in a 16-bit binary format. These Divisor Latches must be loaded during
initialization to ensure proper operation of the Baud Rate Generator. If both Divisor
Latches are loaded with 0, the 16X output clock is stopped. Upon loading either of the
Divisor latches, a 16-bit baud counter is immediately loaded. This prevents long counts
on initial load. Access to the Divisor latch may be done with a word write.
The baud rate of the data shifted in/out of the UART is given by:
For example, if UART_CLK is 14.7456MHz and the divisor is 96, the baud rate is 9600.
A Divisor value of 0 in the Divisor Latch Register is not allowed. The reset value of the
divisor
is 02.
