UART Registers
19.5.1.35 Divisor Latches Low Register (DLL)
The divisor latches low register (DLL) with the DLH register stores the 14-bit divisor for generation of the
baud clock in the baud rate generator. DLH stores the most-significant part of the divisor, DLL stores the
least-significant part of the divisor. The DLL register is shown in
and described in
NOTE:
DLL and DLH can be written to only before sleep mode is enabled (before IER[4] is set).

Divisor latches low. Stores the 8 LSB divisor value.
19.5.1.36 Divisor Latches High Register (DLH)
The divisor latches high register (DLH) with the DLL register stores the 14-bit divisor for generation of the
baud clock in the baud rate generator. DLH stores the most-significant part of the divisor, DLL stores the
least-significant part of the divisor. The DLH register is shown in
