This is a bit of drive-by comment, but "manual mode" usually
means there is a person "a man" pulling levers and pushing
buttons. There is nothing manual inside a computer system.

I think the more appropriate term is "polling mode" which is
what we call code that read registers directly waiting for status
flags rather than relying on IRQs or DMA flows.
