The Universal Synchronous Asynchronous Receiver
Transmitter (USART) is also known as a Serial
Communications Interface or SCI. The USART can be
configured as a full-duplex asynchronous system that
can communicate with peripheral devices such as CRT
terminals and personal computers, or it can be config-
ured as a half-duplex synchronous system that can
communicate with peripheral devices such as A/D or D/
A integrated circuits, Serial EEPROMs, etc.

SYNC
The USART can be configured in the following modes:
• Asynchronous (full-duplex)
• Synchronous - Master (half-duplex)
• Synchronous - Slave (half-duplex)
Bit SPEN (RCSTA<7>), and bits TRISB<2:1>, have to
be set in order to configure pins RB2/TX/CK and RB1/
RX/DT as the Universal Synchronous Asynchronous
Receiver Transmitter.
Register 12-1 shows the Transmit Status and Control
Register (TXSTA) and Register 12-2 shows the
Receive Status and Control Register (RCSTA).
