Test Modes
Normal Mode
Automatic Echo Mode
Local Loopback Mode
The USART can be programmed to operate in three different test modes. The internal loopback
capability allows on-board diagnostics. In the loopback mode the USART interface pins are dis-
connected or not and reconfigured for loopback internally or externally.
Normal mode connects the RXD pin on the receiver input and the transmitter output on the TXD
pin.
Figure 26-40. 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
no effect on the TXD pin. The RXD pin is still connected to the receiver input, thus the receiver
remains active.
Figure 26-41. Automatic Echo Mode Configuration
Local loopback mode connects the output of the transmitter directly to the input of the receiver,
as shown in
no effect on the receiver and the TXD pin is continuously driven high, as in idle state.
