their normal modem control inputs pins, and instead are connected internally to RTS,
DTR, MCR[3] (OP2) and MCR[2] (OP1). Loop-back test data is entered into the
transmit holding register via the user data bus interface, D0-D7. The transmit UART
serializes the data and passes the serial data to the receive UART via the internal
loop-back connection. The receive UART converts the serial data back into parallel
data that is then made available at the user data interface D0-D7. The user optionally
compares the received data to the initial transmitted data for verifying error-free
operation of the UART TX/RX circuits.
In this mode, the receiver and transmitter interrupts are fully operational. The Modem
Control Interrupts are also operational.
