When I need to have a read/write interface I usually have 1) An lpm_decode (enabled with cs), 2) A MUX (selected with the address bits), 3) registers enabled by the lpm_decode logic.

This simple mix allows you to do anything a PIO can plus allows you to take the functionality of many PIOs and stick them altogether implemented in their own address range.

ppk031000 if you like I can send you an example of this (it&#39;s on my home machine so email me if you want it, otherwise I&#39;ll forget).
