7.5 Line Control Register (LCR)
Table 13.
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.

Description
Divisor latch enable. The internal baud rate counter latch and Enhanced
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.

Description
INT status.
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
Rev. 5 — 19 January 2011
logic 0 = an interrupt is pending and the ISR contents may be used as a
pointer to the appropriate interrupt service routine
logic 1 = no interrupt pending (normal default condition)
