converts the serial data back into parallel data that is then made available at the user data
interface D0 through 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.
