SMALLEST 2.25V TO 5.5V UART WITH 16-BYTE FIFO AND POWERSAVE
REV. 1.4.2
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
Baud rate generator divisor (DLL/DLM) 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. This bit has no functionality in the 24-QFN package except in internal loopback
mode.
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. This bit
has no functionality in the 24-QFN package except in internal loopback mode.
Logic 0 = Force RTS# output to a logic 1 (default).
Logic 1 = Force RTS# output to a logic 0.
MCR[2]: Invert Infrared RX Data or OP1# (legacy term)
If IrDA mode is enabled by setting MCR[6]=1 and if EFR[4] = 1, this bit acts as ’Invert Infrared RX data’
command. If EFR[4] = 0 or in internal loopback mode, this bit functions like the OP1# in the 16C550.
Logic 0 = Select RX input as active-low encoded IrDA data (if IrDA Mode is enabled by setting MCR[6] = 1
and EFR[4] = 1) (default).
Logic 1 = Select RX input as active-high encoded IrDA data (if MCR[6] = 1 and EFR[4] = 1). In this mode, this
bit is write-only.
In the Internal Loopback Mode, this bit controls the state of the modem input RI# bit in the MSR register as
shown in
MCR[3]: INT Output Enable or OP2# (legacy term)
This bit enables and disables the operation of interrupt output, INT in the Intel mode. It has no function in the
Motorola mode.
Logic 0 = INT output disabled (three state mode) (default).
Logic 1 = INT output enabled (active mode).
In the Internal Loopback Mode, this bit functions like the OP2# in the 16C550 and is used to set the state of the
modem input CD# bit in the MSR register.
