The Universal Asynchronous Receiver Transmitter
(UART) module is one of the serial I/O modules
available in the dsPIC33FJ12MC201/202 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
interfaces. The module also supports a hardware flow
control option with the UxCTS and UxRTS pins and
also includes an IrDA
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
