It actually helped a lot.Even though the book I'm reading doesn't use that macro,it just uses a hex value to specify what and where to move,I understand it now.Thanks a lot!
But that is how the data looks in a register? It's read from right to left?
I thought only the shuffle command is read from right to left.
you know,if you'd give a shuffle command like 1,3,5,9 it would be read 9,5,3,1.But the data in the register is also put from right to left?
I mean does it look like this?
127.................................0 ?
