Introduction
The Universal Synchronous Asynchronous Receiver Transmitter (USART) module is one of the
two serial I/O modules (other is the SSP module). The USART is also known as a Serial Com-
munications Interface or SCI. The USART can be configured as a full duplex asynchronous sys-
tem 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)
The SPEN bit (RCSTA<7>), and the TRIS bits, have to be set in order to configure the TX/CK and
RX/DT pins for the USART.
