Local Loopback Mode
Remote Loopback Mode
Local loopback mode connects the output of the transmitter directly to the input of the receiver,
as shown in
the receiver and the TXD pin is continuously driven high, as in idle state.
Remote loopback mode directly connects the RXD pin to the TXD pin, as shown in
The transmitter and the receiver are disabled and have no effect. This mode allows bit-by-bit
retransmission.
