I think you need to give us some information on what device you are writing a driver for.

When I started programming the Zilog Z80, I learned the full Z80 technical manual by reading it twice.
When I switched to the Z8, I read the Z8 technical manual from cover to cover several times.
When I switched to 80x86 assembly language I read several books and manuals cover to cover. Several times. Plus of course the DOS manuals.
When I switched to Linux and Mocka I read several books on Modula-2 several times.

It will not be enough to read a few lines and then come up with the essence of a big circuit. You will need to study the material... REALLY study! Count on studying for monts on end before you can do anything meaningful.
