The Universal Asynchronous Receiver Transmitter
(UART) module is one of the serial I/O modules avail-
able in the PIC24HJXXXGPX06A/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 inter-
faces. The module also supports a hardware flow con-
trol option with the UxCTS and UxRTS pins and also
includes an IrDA
The primary features of the UART module are:
