18.0
The UART module is one of the serial I/O modules
available in PIC32MX1XX/2XX 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 and IrDA
ports the hardware flow control option, with UxCTS and
UxRTS pins, and also includes an IrDA encoder and
decoder.

Preliminary
in
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 38 bps to 10 Mbps at 40
• 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 Protocol support
• IrDA encoder and decoder with 16x baud clock
