This read/write bit enables loop mode operation. In loop mode the RxD pin is disconnected from the
ESCI, 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 ESCI and the ESCI baud rate generator. Clearing ENSCI sets the SCTE
and TC bits in ESCI status register 1 and disables transmitter interrupts. Reset clears the ENSCI bit.
This read/write bit reverses the polarity of transmitted data. Reset clears the TXINV bit.
This read/write bit determines whether ESCI characters are eight or nine bits long (See
Table

1 = Loop mode enabled
0 = Normal operation enabled

Setting the TXINV bit inverts all transmitted values including idle, break,
start, and stop bits.
