The Addressable Universal Synchronous Asynchronous
Receiver Transmitter (AUSART) module is one of the
two serial I/O modules. (AUSART is also known as a
Serial Communications Interface or SCI.) The AUSART
can be configured as a full-duplex asynchronous system
that can communicate with peripheral devices, such as
CRT terminals and personal computers, or it can be
configured as a half-duplex synchronous system that
can communicate with peripheral devices, such as A/D
or D/A integrated circuits, serial EEPROMs, etc.

The AUSART can be configured in the following
modes:
• Asynchronous (full-duplex)
• Synchronous – Master (half-duplex)
• Synchronous – Slave (half-duplex)
Bit SPEN (RCSTA<7>) and bits TRISC<7:6> have
to be set in order to configure pins RC6/TX/CK and
RC7/RX/DT
Asynchronous Receiver Transmitter.
The AUSART module also has a multi-processor
communication capability using 9-bit address detection.
