Loopback. Enable the local Loopback mode (diagnostics). In this mode the
transmitter output (TXn) and the receiver input (RXn), CTS, DSR, CD, and
RI are disconnected from the SC16C554B/554DB I/O pins. Internally the
modem data and control pins are connected into a loopback data
configuration (see
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.
mode.
this bit is used to write the state of the modem RI interface signal via OP1.
Automatic RTS may be used for hardware flow control by enabling MCR[5].
logic 0 = disable Loopback mode (normal default condition)
logic 1 = enable local Loopback mode (diagnostics)
logic 0 = forces INTA to INTD outputs to the 3-state mode during the
16 mode (normal default condition). In the Loopback mode, sets OP2
(CD) internally to a logic 1.
logic 1 = forces the INTA to INTD outputs to the active mode during the
16 mode. In the Loopback 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
