The Universal Asynchronous Receiver Transmitter
(UART) module is one of the serial I/O modules available
in the PIC24F device family. The UART is a full-duplex,
asynchronous system that can communicate with
peripheral devices, such as personal computers,
LIN/J2602, 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
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
• Hardware Flow Control Option with the UxCTS

This data sheet summarizes the features
of this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to the
“PIC24F
Section 21. “UART” (DS39708). The
information in this data sheet supersedes
the information in the FRM.
The UART inputs and outputs must all be assigned to available RPn/RPIn pins before use. See Section 10.4
“Peripheral Pin Select (PPS)” for more information.
