The dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/
50X, and PIC24EPXXXGP/MC20X family of devices
contain two UART modules.
The Universal Asynchronous Receiver Transmitter
(UART) module is one of the serial I/O modules
available
dsPIC33EPXXXMC20X/50X, and PIC24EPXXXGP/
MC20X 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
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
• Hardware flow control option with UxCTS and
• Fully integrated Baud Rate Generator with 16-bit
• Baud rates ranging from 4.375 Mbps to 67 bps at
• Baud rates ranging from 17.5 Mbps to 267 bps at
• 4-deep First-In First-Out (FIFO) Transmit Data
• 4-deep FIFO Receive Data buffer
• Parity, framing and buffer overrun error detection
• Support for 9-bit mode with Address Detect
• Transmit and Receive interrupts
• A separate interrupt for all UART error conditions
• Loopback mode for diagnostic support
• Support for Sync and Break characters
• Support for automatic baud rate detection
• IrDA
