UART Modules
16.3.11 UART Divider Upper/Lower Registers (UDUn/UDLn)
The UDUn registers (formerly called UBG1n) hold the MSB, and the UDLn registers (formerly UBG2n)
hold the LSB of the preload value. UDUn and UDLn concatenate to provide a divider to CLKIN for
transmitter/receiver operation, as described in
16.3.12 UART Autobaud Registers (UABUn/UABLn)
The UABUn registers hold the MSB, and the UABLn registers hold the LSB of the calculated baud rate.
If UCRn[ENAB] is set, the value in these registers is automatically loaded into UDUn and UDLn.

The minimum value that can be loaded on the concatenation of UDUn with
UDLn is 0x0002. Both UDUn and UDLn are write-only and cannot be read
by the CPU.
