The Line Control Register is used to specify the asyn-
chronous data communication format. The word or
character length, the number of stop bits, and the par-
ity are selected by writing the appropriate bits in this
register.
LCR[1-0]: TX and RX Word Length Select
These two bits specify the word length to be transmit-
ted or received.

LCR[2]: TX and RX Stop-bit Length Select
The length of stop bit is specified by this bit in con-
junction with the programmed word length.
LCR[3]: TX and RX Parity Select
Parity or no parity can be selected via this bit. The
parity bit is a simple way used in communications for
data integrity check. See Table 11 for parity selection
summary below.
Logic 0 = No parity.
Logic 1 = A parity bit is generated during the trans-
mission while the receiver checks for parity error of
the data character received.
