The UART module is one of the serial I/O modules
available in PIC32MX3XX/4XX family devices. The
UART is a full-duplex, asynchronous communication
channel that communicates with peripheral devices
and personal computers through protocols such as RS-
232, RS-485, LIN 1.2 and IrDA
ports the hardware flow control option, with UxCTS and
UxRTS pins, and also includes an IrDA encoder and
decoder.

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 auto-baud feature
• Hardware flow control option
• Fully integrated Baud Rate Generator (BRG) with
• Baud rates ranging from 76 bps to 20 Mbps at 80
• 4-level-deep First-In-First-Out (FIFO) Transmit
• 4-level-deep FIFO Receive Data Buffer
• Parity, framing and buffer overrun error detection
• Support for interrupt only on address detect (9th
• Separate transmit and receive interrupts
• Loopback mode for diagnostic support
• LIN 1.2 protocol support
• IrDA encoder and decoder with 16x baud clock
Figure 19-1 shows a simplified block diagram of the
UART.
