This read/write bit enables loop mode operation for the SCI only. In loop mode the RxD pin is
disconnected from the SCI, and the transmitter output goes into the receiver input. Both the transmitter
and the receiver must be enabled to use loop mode. The infrared encoder/decoder is not in the loop.
Reset clears the LOOPS bit.
This read/write bit enables the SCI and the SCI baud rate generator. Clearing ENSCI sets the SCTE
and TC bits in SCI status register 1 and disables transmitter interrupts. Reset clears the ENSCI bit.
1 = Loop mode enabled
0 = Normal operation enabled
1 = SCI enabled
0 = SCI disabled
