The USART module is a serial I/O module. 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 (RCSTA<7>) bit has to be set in order to
configure RA4 and RA5 as the Serial Communication
Interface.
The USART module will control the direction of the
RA4/RX/DT and RA5/TX/CK pins, depending on the
states of the USART configuration bits in the RCSTA
and TXSTA registers. The bits that control I/O direction
are:
• SPEN
• TXEN
• SREN
• CREN
• CSRC
The Transmit Status And Control Register is shown in
Figure 13-1, while the Receive Status And Control
Register is shown in Figure 13-2.
