The Samsung microcontroller has a DMA controller with it. the UART can be
configured to work along with the UART chip. This is called DMA mode of the
UART chip. With this you can configure to get the interrupt after certian
number of bytes are received instead of single byte interrupt.
hope this helps.

Hi,
I have set, ARM e7t port to Baud 38400,
I think, the board interrupts the ARM core
for every character read. (instead of for a
bunch of characters)
And because of this, I am loosing some
characters, Can anyone give me, any solution
for this problem ?
