Hello colleagues,
I'm using TI's Stellaris LM3S1621 MCU.
Tell me please if it is possible to start DMA transaction from external interrupt (triggered from any GPIO)? For example I'd like to take one byte from PORTA and save it in external SDRAM. Besides this frequency of starting pulses is very big so interrupt mechanism is not applicable.
Thank you.
