The Enhanced Universal Synchronous Asynchronous
Receiver Transmitter (EUSART) module is one of two
serial I/O modules. (Generically, the EUSART 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 and so on.
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.
All members of the PIC18F46J50 Family are equipped
with two independent EUSART modules, referred to as
EUSART1 and EUSART2. They can be configured in
the following modes:
• Asynchronous (full-duplex) with:
• Synchronous – Master (half-duplex) with
• Synchronous – Slave (half-duplex) with selectable

The pins of EUSART1 and EUSART2 are multiplexed
with the functions of PORTC (RC6/TX1/CK1/RP17 and
RC7/RX1/DT1/SDO1/RP18)
(RPn1/TX2/CK2 and RPn2/RX2/DT2), respectively. In
order to configure these pins as an EUSART:
• For EUSART1:
• For EUSART2:
The TXx/CKx I/O pins have an optional open-drain
output capability. By default, when this pin is used by
the EUSART as an output, it will function as a standard
push-pull CMOS output. The TXx/CKx I/O pins’
open-drain, output feature can be enabled by setting
the corresponding UxOD bit in the ODCON2 register.
For more details, see Section 18.3.3 “Open-Drain
Output Option”.
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 covered in detail in Register 19-1,
Register 19-2 and Register 19-3, 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.
Thus, “RCSTAx” might refer to the
Receive
EUSART1 or EUSART2.
