LOOPS — Loop Select Bit
The RXD pin becomes general-purpose I/O when LOOPS = 1,
regardless of the state of the RSRC bit. DDRSC0 in SCIDDR is the data
direction bit for the RXD pin.

Write:
This read/write control bit switches the SCI between normal mode
and loop mode. Reset clears LOOPS.
The SCI operates normally (LOOPS = 0, RSRC = X) when the output
of its transmitter is connected to the TXD pin, and the input of its
receiver is connected to the RXD pin.
In loop mode (LOOPS =1, RSRC = 0), the input to the SCI receiver is
internally disconnected from the RXD pin logic and instead connected
to the output of the SCI transmitter. The behavior of TXD is governed
by the DDRSC1 bit in SCIDDR. If DDRSC1 = 1, the TXD pin is driven
with the output of the SCI transmitter. If DDRSC1 = 0, the TXD pin
idles high. See
For either loop mode or single-wire mode to function, both the SCI
receiver and transmitter must be enabled by setting the RE and TE
bits in SCIxCR2.
