This Module can select a Device when issuing an OUT command. Available devices can then be routed through the 5 spare pins or 6 extended ones by jumper cables.
Total devices that can be selected are 16 with these addresses: 00h,08h,10h,18h,20h,28h,30h,38h, 40h,48h,50h,58h,60h,68h,70h,78h. The three lower bits can select a register (total 8) in these devices. The two upper bits are filtered. Of course you can use the A0-A2 bits to filter further and use them to select more devices.
