The Universal Synchronous Asynchronous Receiver
Transmitter (USART) module is one of the two serial
I/O modules. (USART is also known as a Serial Com-
munications Interface or SCI.) The USART can be con-
figured as a full-duplex asynchronous system that can
communicate with peripheral devices, such as CRT
terminals and personal computers. It can also be con-
figured 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 EUSART module implements additional features,
including automatic baud rate detection and calibra-
tion, automatic wake-up on Sync Break reception 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 selectable

Preliminary
The pins of the Enhanced USART are multiplexed with
PORTC. In order to configure RC6/TX/CK and
RC7/RX/DT as a USART:
• bit SPEN (RCSTA<7>) must be set (= 1)
• bit TRISC<7> must be set (= 1)
• bit TRISC<6> must be cleared (= 0) for
The operation of the Enhanced USART module is
controlled through three registers:
• Transmit Status and Control (TXSTA)
• Receive Status and Control (RCSTA)
• Baud Rate Control (BAUDCON)
These are detailed on the following pages in
Register 18-1,
respectively.
Asynchronous and Synchronous Master modes,
or set (= 1) for Synchronous Slave mode
Note:
The EUSART control will automatically
reconfigure the pin from input to output as
needed.
