The Universal Asynchronous Receiver Transmitter
(UART) module is one of the serial I/O modules avail-
able in the PIC24HJXXXGPX06/X08/X10 device fam-
ily. 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:
• Full-Duplex, 8 or 9-bit Data Transmission through
• Even, Odd or No Parity Options (for 8-bit data)
• One or Two Stop bits

Note 1: Both UART1 and UART2 can trigger a DMA data transfer. If U1TX, U1RX, U2TX or U2RX is selected as
2: If DMA transfers are required, the UART TX/RX FIFO buffer must be set to a size of 1 byte/word
