made available at the user data interface D0 to 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. However, the interrupts can only be read using
lower four bits of the Modem Status Register (MSR[3:0]) instead of the four Modem Status
Register bits 7:4. The interrupts are still controlled by the IER.
