As the same reason, + (16-k)/16 division function in the baud rate generator of SIO0 can not be
used to generate 115.2 kbps baud rate.
Also when the 38.4 kbps and 1/16 pulse width, + (16-k)/16 division function can not be used. Table
3.9.6 shows Baud rate and pulse width for (16 – k) / 16 division function.
