This read/write bit enables loop mode operation. In loop mode the
PTB0/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. 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.
