The Universal Asynchronous Receiver Transmitter
(UART) module is one of the serial I/O modules
available
PIC24HJ64GPX02/X04 and PIC24HJ128GPX02/X04
device family. The UART is a full-duplex asynchronous
system that can 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

Preliminary
of
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 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
A simplified block diagram of the UART module is
shown in Figure 18-1. The UART module consists of
these key hardware elements:
• Baud Rate Generator
• Asynchronous Transmitter
• Asynchronous Receiver
