The Universal Asynchronous Receiver Transmitter
(UART) module is one of the serial I/O modules
available
PIC24HJ16GP304 device family. The UART is a
full-duplex
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-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 10 Mbps to 38 bps at 40
• 4-deep first-in-first-out (FIFO) Transmit Data Buffer
• 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
