The Universal Asynchronous Receiver Transmitter
(UART) module is one of the serial I/O modules
available in the PIC24FJ16MC101/102 device family.
The UART is a full-duplex asynchronous system that
can communicate with peripheral devices, such as
personal computers, LIN 2.0, and 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-bit or 9-bit Data Transmission
• 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 0.4 Mbps to 6 bps at 16x
• Baud rates ranging from 1.6 Mbps to 24.4 bps at 4x
• 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
• 16x baud clock output for IrDA
