Modem Control Register bits description
Description
Loop-back. Enable the local loop-back mode (diagnostics). In this mode the
transmitter output (TX) and the receiver input (RX), CTS, DSR, CD, and RI are
disconnected from the SC16C654B/654DB I/O pins. Internally the modem
data and control pins are connected into a loop-back data configuration; see
Figure
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.
OP2, INTx enable. Used to control the modem CD signal in the loop-back
mode.
OP1. This bit is used in the Loop-back mode only. In the loop-back mode, this
bit is used to write the state of the modem RI interface signal via OP1.
RTS
Automatic RTS may be used for hardware flow control by enabling EFR[6].

5 V, 3.3 V and 2.5 V quad UART, 5 Mbit/s (max.) with 64-byte FIFOs
logic 0 = disable loop-back mode (normal default condition)
logic 1 = enable local loop-back mode (diagnostics)
logic 0 = forces INTA-INTD outputs to the 3-state mode during the 16 mode
(normal default condition). In the loop-back mode, sets OP2 (CD) internally
to a logic 1.
logic 1 = forces the INTA-INTD outputs to the active mode during the
16 mode. In the loop-back mode, sets OP2 (CD) internally to a logic 0.
logic 0 = force RTS output to a logic 1 (normal default condition)
logic 1 = force RTS output to a logic 0
logic 0 = force DTR output to a logic 1 (normal default condition)
logic 1 = force DTR output to a logic 0
