The UART module is one of the serial I/O modules
available in PIC32MX5XX/6XX/7XX family devices.
The UART is a full-duplex, asynchronous communica-
tion channel that communicates with peripheral
devices and personal computers through protocols,
such as RS-232, RS-485, LIN 1.2 and IrDA
module also supports the hardware flow control option,
with UxCTS and UxRTS pins, and also includes an
IrDA encoder and decoder.

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
• 8-level deep First-In-First-Out (FIFO) transmit
• 8-level deep FIFO receive data buffer
• Parity, framing and buffer overrun error detection
• Support for interrupt-only on address detect
• Separate transmit and receive interrupts
• Loopback mode for diagnostic support
• LIN 1.2 Protocol support
• IrDA encoder and decoder with 16x baud clock
