18.0
The Universal Asynchronous Receiver Transmitter
(UART) module is one of the serial I/O modules
available
dsPIC33FJ64GPX02/X04, and dsPIC33FJ128GPX02/
X04 device family. The UART is a full-duplex
asynchronous system that can communicate with
peripheral devices, such as personal computers,
LIN 2.0, 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.

Note 1: This data sheet summarizes the features
Note 1: Both UART1 and UART2 can trigger a DMA data transfer.
2: Some registers and associated bits
2: If DMA transfers are required, the UART TX/RX FIFO buffer must be set to a size of 1 byte/word

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
• 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
