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 ter-
minals and personal computers, or it can be configured
as a half-duplex synchronous system that can commu-
nicate 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)
In order to configure pins RC6/TX/CK and RC7/RX/DT
as the Universal Synchronous Asynchronous Receiver
Transmitter:
• bit SPEN (RCSTA<7>) must be set (= 1),
• bit TRISC<6> must be cleared (= 0), and
• bit TRISC<7> must be set (=1).
Register 16-1 shows the Transmit Status and Control
Register (TXSTA) and Register 16-2 shows the
Receive Status and Control Register (RCSTA).
