Programming Notes
In order to determine the UART baud
rate that will result from a particular
setting of the baud rate divisor latch,
the 16x baud clock is divided by 16 to
give a normalized baud rate. Because
the standard 16x baud clock runs at
1.8432 MHz, the “normalized” baud
rate is 115200. This rate is then
divided by the value of the 16-bit baud
clock divisor latch register. It is invalid
to program a baud rate divisor of 0.
The baud rate divisor latch, being a
16-bit value, provides for up to 64k–1
different baud rates (0 is not a valid
baud rate). However, only a few of the
available rates are ever used in
common practice. See the following
table for the commonly used baud
rates along with the baud rate divisor
required to achieve them:
