The Universal Asynchronous Receiver Transmitter
(UART) module is one of the serial I/O modules
available in the dsPIC30F1010/202X device family.
The UART is a full-duplex asynchronous system that
can communicate with peripheral devices, such as
personal computers, LIN, RS-232 and RS-485 inter-
faces. The module also includes an IrDA encoder and
decoder
The primary features of the UART module are:
• Full-Duplex 8 or 9-bit Data Transmission through
• Even, Odd or No Parity Options (for 8-bit data)
• One or Two Stop bits
• Fully Integrated Baud Rate Generator with 16-bit
