5 V, 3.3 V and 2.5 V UART with 16-byte FIFOs
7.6 Modem Control Register (MCR)
This register controls the interface with the modem or a peripheral device.

MCR[4]
Loopback. Enable the local loopback mode (diagnostics). In this mode the
transmitter output (TX) and the receiver input (RX), CTS, DSR, DCD, and
RI are disconnected from the SC16C550B I/O pins. Internally the modem
data and control pins are connected into a loopback data conguration
(see Figure 11). In this mode, the receiver and transmitter interrupts
remain fully operational. The Modem Control Interrupts are also
operational, but the interrupts’ sources are switched to the lower four bits
of the Modem Control. Interrupts continue to be controlled by the IER
register.
logic 0 = disable loopback mode (normal default condition)
logic 1 = enable local loopback mode (diagnostics)
3
MCR[3]
OUT2. Used to control the modem DCD signal in the loopback mode.
logic 0 = OUT2 is at logic 1. In the loopback mode, sets OUT2 (DCD)
internally to a logic 1.
logic 1 = OUT2 is at logic 0. In the loopback mode, sets OUT2 (DCD)
internally to a logic 0.
2
MCR[2]
OUT1. This bit is used in the Loopback mode only. In the loopback mode,
this bit is used to write the state of the modem RI interface signal via
OUT1.
1
MCR[1]
RTS
logic 0 = force RTS output to a logic 1 (normal default condition)
logic 1 = force RTS output to a logic 0
0
MCR[0]
DTR
logic 0 = force DTR output to a logic 1 (normal default condition)
logic 1 = force DTR output to a logic 0
