The Enhanced Universal Synchronous Asynchronous
Receiver Transmitter (EUSART) module is one of two
serial I/O modules. (Generically, the USART is also
known as a Serial Communications Interface or SCI.)
The EUSART can be configured as a full-duplex
asynchronous system that can communicate with
peripheral devices, such as CRT terminals and
personal computers. It can also 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 Enhanced USART module implements additional
features, including automatic baud rate detection and
calibration, automatic wake-up on Sync Break recep-
tion and 12-bit Break Character transmit. These make
it ideally suited for use in Local Interconnect Network
bus (LIN bus) systems.
The EUSART can be configured in the following
modes:
• Asynchronous (full duplex) with:
• Synchronous – Master (half duplex) with
• Synchronous – Slave (half duplex) with

TRANSMITTER (EUSART)
The pins of EUSART1 and EUSART2 are multiplexed
with the functions of PORTC (RC6/TX1/CK1 and RC7/
RX1/DT1) and PORTG (RG1/TX2/CK2 and RG2/RX2/
DT2), respectively. In order to configure these pins as
an EUSART:
• For EUSART1:
• For EUSART2:
The operation of each Enhanced USART module is
controlled through three registers:
• Transmit Status and Control (TXSTAx)
• Receive Status and Control (RCSTAx)
• Baud Rate Control (BAUDCONx)
These are detailed on the following pages in
Register 20-1,
respectively.

The EUSART control will automatically
reconfigure the pin from input to output as
needed.
Throughout this section, references to
register and bit names that may be associ-
ated with a specific EUSART module are
referred to generically by the use of ‘x’ in
place of the specific module number.
