The Universal Asynchronous Receiver Transmitter
(UART) module is one of the serial I/O modules
available
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
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

the UxTX and UxRX pins
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 (i.e.,
