LOOPS — SCI LOOP Mode/Single Wire Mode Enable
WOMS — Wired-Or Mode for Serial Pins
If the DDRS bit associated with the TXD pin is set during the LOOPS
= 1, the TXD pin outputs the SCI waveform. If the DDRS bit
associated with the TXD pin is clear during the LOOPS = 1, the TXD
pin becomes high (IDLE line state) for RSRC = 0 and high impedance
for RSRC = 1. Refer to
This bit controls the two pins (TXD and RXD) associated with the SCIx
section.

0 = SCI transmit and receive sections operate normally.
1 = SCI receive section is disconnected from the RXD pin and the
0 = Pins operate in a normal mode with both high and low drive

RXD pin is available as general purpose I/O. The receiver input
is determined by the RSRC bit. The transmitter output is
controlled by the associated DDRS bit. Both the transmitter
and the receiver must be enabled to use the LOOP or the
single wire mode.
capability. To affect the RXD bit, that bit would have to be
configured as an output (via DDRS0/2) which is the single wire
case when using the SCI. WOMS bit still affects general-
purpose output on TXD and RXD pins when SCIx is not using
these pins.
