I take it that you are talking about the Texas Instruments UART with that part number. It's a pretty standard 8250 descendant, with 16 byte transmit and receive FIFOs.

What I don't understand is "DMA mode 1". What microprocessor, microcontroller, or DMA controller are you talking about? If it can generate a chip select and read or write strobes, or you can add external logic to it to generate them, then yes, of course, it can, if the timing is compatible with the UART's bus cycle requirements.

If not, post again and provide more detail about "DMA mode 1".
