Product data sheet
Programming the baud rate generator registers CLKPRES, DLM (MSB) and DLL (LSB)
provides a user capability for selecting the desired final baud rate. The example in
shows the selectable baud rate table available when using a 1.8432 MHz external clock
input when MCR[7] = 0, and CLKPRES = 0x00.
