Product data
7.5 Line Control Register (LCR)
The Line Control Register is used to specify the asynchronous data communication
format. The word length, the number of stop bits, and the parity are selected by
writing the appropriate bits in this register.

Dual UART with 32-byte FIFOs and IrDA encoder/decoder
Description
Divisor latch enable. The internal baud rate counter latch and
Enhance Feature mode enable.
Set break. When enabled, the Break control bit causes a break
condition to be transmitted (the TX output is forced to a logic 0
state). This condition exists until disabled by setting LCR[6] to a
logic 0.
Programs the parity conditions (see
Stop bits. The length of stop bit is specified by this bit in
conjunction with the programmed word length (see
Word length bits 1, 0. These two bits specify the word length to be
transmitted or received (see
Logic 0 = Divisor latch disabled (normal default condition).
Logic 1 = Divisor latch enabled.
Logic 0 = no TX break condition (normal default condition)
Logic 1 = forces the transmitter output (TX) to a logic 0 for
alerting the remote receiver to a line break condition.
Logic 0 or cleared = default condition.
Logic 0 or cleared = default condition.
