The Universal Asynchronous Receiver Transmitter
(UART) module is one of the serial I/O modules avail-
able in this PIC24F 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. This module also
supports a hardware flow control option with the U1CTS
and U1RTS pins, and also includes an IrDA
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 Flow Control Option with U1CTS and
