Hello,
I was reading some documents about the DMA and they were talking about 'Flip-Flop register'. What is the role of this register?
Thank you for any help.

Hi,
The DMA has 16 bit registers but the port is only 8bit so to make sure that you are writing the correct 8 bits you initialise the ports by writing any value to the flipFlop register. Then The Lo byte is the first written.

Hope this helps
