Automatic Echo Mode
Local Loopback Mode
Remote Loopback Mode
Figure 31-30. Normal Mode Configuration
Automatic echo mode allows bit-by-bit retransmission. When a bit is received on the RXD pin, it
is sent to the TXD pin, as shown in
the TXD pin. The RXD pin is still connected to the receiver input, thus the receiver remains
active.
Figure 31-31. Automatic Echo Mode Configuration
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.
Figure 31-32. Local Loopback Mode Configuration
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.
