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.
[1]
When LCR[7] = 1, the general register set cannot be accessed until LCR[7] = 0.

Line Control Register bits description

Description
LCR[7]
[1]
Divisor latch enable. The internal baud rate counter latch and Enhance
Feature mode enable.
Logic 0 = Divisor latch disabled (normal default condition).
Logic 1 = Divisor latch and enhanced feature register enabled.
LCR[6]
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.
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.
LCR[5]
Set parity. If the parity bit is enabled, LCR[5] selects the forced parity
format. Programs the parity conditions (see
Table 15
).
Logic 0 = parity is not forced (normal default condition).
LCR[5] = logic 1 and LCR[4] = logic 0: parity bit is forced to a logical 1
for the transmit and receive data.
LCR[5] = logic 1 and LCR[4] = logic 1: parity bit is forced to a logical 0
for the transmit and receive data.
LCR[4]
Even parity. If the parity bit is enabled with LCR[3] set to a logic 1,
LCR[4] selects the even or odd parity format.
Logic 0 = ODD Parity is generated by forcing an odd number of
logic 1s in the transmitted data. The receiver must be programmed to
check the same format (normal default condition).
Logic 1 = EVEN Parity is generated by forcing an even number of
logic 1s in the transmitted data. The receiver must be programmed to
check the same format.
LCR[3]
Parity enable. Parity or no parity can be selected via this bit.
Logic 0 = no parity (normal default condition).
Logic 1 = a parity bit is generated during the transmission, receiver
checks the data and parity for transmission errors.
LCR[2]
Stop bits. The length of stop bit is specified by this bit in conjunction with
the programmed word length (see
Table 16
).
Logic 0 or cleared = default condition.
LCR[1-0]
Word length bits 1, 0. These two bits specify the word length to be
transmitted or received (see
Table 17
).
Logic 0 or cleared = default condition.
