The Universal Asynchronous Receiver Transmitter
(UART) module is one of the serial I/O modules
available in the dsPIC33FJXXXMCX06A/X08A/X10A
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 hard-
ware flow control option with the UxCTS and UxRTS
pins and also includes an IrDA

Preliminary
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
• Supports Automatic Baud Rate Detection
• IrDA
• 16x Baud Clock Output for IrDA
A simplified block diagram of the UART is shown in
Figure 20-1. The UART module consists of these key
important hardware elements:
• Baud Rate Generator
• Asynchronous Transmitter
• Asynchronous Receiver
