11.3.1.3. Baud Rate Can Be Changed By Software Setting
When this setting is on, the hardware includes a 16-bit divisor register at address offset 4. The divisor register is writable, so the baud rate can be changed by writing a new value to this register.
When this setting is off, the UART hardware does not include a divisor register. The UART hardware implements a constant baud divisor, and the value cannot be changed after system generation. In this case, writing to address offset 4 has no effect, and reading from address offset 4 produces an undefined result.
