RDAIE [0]: Receive Data Available Interrupt (Irpt_RDA) Enable and
Time-out Interrupt (Irpt_TOUT) Enable
0 = Mask off Irpt_RDA and Irpt_TOUT
1 = Enable Irpt_RDA and Irpt_TOUT
Divider Latch (Low Byte) Register (DLL)
Baud Rate Divisor (Low Byte) [7:0]
The low byte of the baud rate divider
Divisor Latch (High Byte) Register (DLM)
Baud Rate Divisor (High Byte) [7:0]
The high byte of the baud rate divider
This 16-bit divider {DLM, DLL} is used to determine the baud rate as follows
Baud Rate = Crystal Clock / {16 * [Divisor + 2]}
Note: This definition is different from 16550
