Serial Communications Interface
Technical Data

NOTE:
Address:
LOOPS — Loop Mode Select Bit
ENSCI — Enable SCI Bit
TXINV — Transmit Inversion Bit
Setting the TXINV bit inverts all transmitted values, including idle, break,
start, and stop bits.
Reset:
Read:
Write:
This read/write bit enables loop mode operation. 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. 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.
This read/write bit reverses the polarity of transmitted data. Reset
clears the TXINV bit.
