The Universal Asynchronous Receiver Transmitter
(UART) module is one of the serial I/O modules
available in the dsPIC33FJXXXGPX06A/X08A/X10A
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. The module also supports a hardware flow
control option with the UxCTS and UxRTS pins and
also includes an IrDA
