How to define the base address for the ACL-8112 ?
The DIP1 to DIP5 in the switch SW1 are one to one corresponding to
the PC AT-bus address line A8 to A4. A9 is always 1 and A0~A3 are
always 0. If you want to change the base address, you can only
change the values of A8 to A4 (the shadow area of below table). The
following table is an example, which shows you how to define the base
address as Hex 220
