Hi everybody!

I am working on a project where a 20 Bit counter would be a great thing
to have.

Does such a beast exist?

What I would like to be able to do is increment/decrement the counter
by putting a pulse on a pin and sending the resulting 20 bit number to
20 pins.

What I am trying to do is access 1 MByte of memory with a micro-controller.
Since the controller only can access 64K I figured I could use a 20 bit
counter.  I will only be accessing the memory sequentially anyway, so the
counter bit would work perfectly..

BTW:  If a 20 Bit counter does not exist, how would one go about building one?

THank you.
