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, 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/J2602 bus) systems.

PIC18F66K80 FAMILY
Port
All members of the PIC18F66K80 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 with the following ports, depending
on the device pin count. See
• For EUSART2:
- Auto-wake-up on character reception
- Auto-baud calibration
- 12-bit Break character transmission
