The Addressable Universal Synchronous Asynchro-
nous Receiver Transmitter (AUSART) module is very
similar in function to the Enhanced USART module,
discussed in the previous chapter. It is provided as an
additional channel for serial communication, with
external devices, for those situations that do not require
Auto-Baud Detection or LIN bus support.
The AUSART can be configured in the following modes:
• Asynchronous (full-duplex)
• Synchronous – Master (half-duplex)
• Synchronous – Slave (half-duplex)

The pins of the AUSART module are multiplexed with
the functions of PORTG (RG1/TX2/CK2/SEG29 and
RG2/RX2/DT2/SEG28, respectively). In order to
configure these pins as an AUSART:
• SPEN bit (RCSTA2<7>) must be set (= 1)
• TRISG<2> bit must be set (= 1)
• TRISG<1> bit must be cleared (= 0) for
• TRISG<1> bit must be set (= 1) for Synchronous
The operation of the Addressable USART module is
controlled through two
RXSTA2. These are detailed in Register 17-1 and
Register 17-2 respectively.

Note:
The AUSART control will automatically
reconfigure the pin from input to output as
needed.
