If you've ever had to write a program which interfaces directly with hardware — perhaps while writing a program for an MCU or embedded system or a kernel driver — you may have noticed a few common patterns in register map behaviour and design. I'm not sure anyone has ever really collected them together, so I decided to make a list of all the ones I can think of.

    Sometimes there is no memory behind the register. The address decode and the r/W line together through an AND gate triggert some action. There is nothing to read back.
