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 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 inte-
grated 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 Asynchro-
nous Receiver Transmitter.

Asynchronous mode:
Don’t care
Synchronous mode:
1
= Master mode (clock generated internally from BRG)
0
= Slave mode (clock from external source)
bit 6
TX9: 9-bit Transmit Enable bit
1
= Selects 9-bit transmission
0
= Selects 8-bit transmission
bit 5
TXEN: Transmit Enable bit
1
= Transmit enabled
0
= Transmit disabled
Note:
SREN/CREN overrides TXEN in Sync mode.
