2.97V TO 5.5V QUAD UART WITH 128-BYTE FIFO
REV. 3.1.0
LCR[6]: Transmit Break Enable
When enabled, the Break control bit causes a break condition to be transmitted (the TX output is forced to a
“space’, logic 0, state). This condition remains, until disabled by setting LCR bit-6 to a logic 0.
Logic 0 = No TX break condition (default).
Logic 1 = Forces the transmitter output (TX) to a “space”, logic 0, for alerting the remote receiver of a line
break condition.
LCR[7]: Baud Rate Divisors Enable
Logic 0 = Data registers are selected (default).
Logic 1 = Divisor latch registers are selected.

Modem Control Register (MCR) or General Purpose Outputs Control - Read/Write
The MCR register is used for controlling the serial/modem interface signals or general purpose inputs/outputs.
MCR[0]: DTR# Output
The DTR# pin is a modem control output. If the modem interface is not used, this output may be used as a
general purpose output.
Logic 0 = Force DTR# output to a logic 1 (default).
Logic 1 = Force DTR# output to a logic 0.
MCR[1]: RTS# Output
The RTS# pin is a modem control output and may be used for automatic hardware flow control by enabled by
EFR bit-6. If the modem interface is not used, this output may be used as a general purpose output.
Logic 0 = Force RTS# output to a logic 1 (default).
Logic 1 = Force RTS# output to a logic 0.
MCR[2]: Reserved
OP1# is not available as an output pin on the 854. But it is available for use during Internal Loopback Mode. In
the Loopback Mode, this bit is used to write the state of the modem RI# interface signal. If OP1# output is
required for RS485 operation, use the XR16C864.
MCR[3]: INT Output Enable
Enable or disable INT outputs to become active or in three-state. This function is associated with the INTSEL
input, see below table for details. This bit is also used to control the OP2# signal during internal loopback
mode. INTSEL pin must be set to a logic zero during 68 mode.
Logic 0 = INT (A-D) outputs disabled (three state) in the 16 mode (default). During loopback mode, it sets
OP2# internally to a logic 1.
Logic 1 = INT (A-D) outputs enabled (active) in the 16 mode. During loopback mode, it sets OP2# internally
to a logic 0.
