UART Line Control Register
This register is used to control the communication control parameters. See

Description
Access to the UART registers at I/O addresses C0h, C1h, D0h and D1h is enabled.
Access to the Baud Rate Generator registers at I/O addresses C0h, C1h, D0h and
D1h is enabled.
Do not send a BREAK signal.
Send Break.
UART sends continuous zeroes on the transmit output from the next bit boundary.
The transmit data in the transmit shift register is ignored. After forcing this bit High,
the
0, the transmit FIFO is cleared. Any new data written to the transmit FIFO during a
break must be written only after the THRE bit of UARTx_LSR register goes High.
This new data is transmitted after the UART recovers from the break. After the break
is removed, the UART recovers from the break for the next BRG edge.
Do not force a parity error.
Force a parity error. When this bit and the parity enable bit (pen) are both 1, an
incorrect parity bit is transmitted with the data byte.

Description
FIFOs are not used.
Receive and transmit FIFOs are used–You must clear the
FIFO logic using bits 1 and 2. First enable the FIFOs by setting
bit 0 to 1 then enable the receiver and transmitter by setting
bits 1 and 2.
