The Universal Asynchronous Receiver Transmitter
(UART) module is one of the serial I/O modules
available in the dsPIC33FJ16(GP/MC)101/102 and
dsPIC33FJ32(GP/MC)101/102/104 device family. The
UART is a full-duplex asynchronous system that can
communicate with peripheral devices, such as
personal computers, LIN/J2602, 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
