UNIVERSAL SYNCHRONOUS
ASYNCHRONOUS RECEIVER
TRANSMITTER (USART)
The Universal Synchronous Asynchronous Receiver
Transmitter (USART) module is one of the two serial
I/O modules. (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
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 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 TRISC<7:6> have to be
set in order to configure pins RC6/TX/CK and
RC7/
RX/DT as the Universal Synchronous Asynchronous
Receiver Transmitter.
