| Note: A total of 48 base address settings are |
| available. The switches are a binary representation |
| of the decimal memory addresses. SW1/6 is the Most |
| Significant Bit and switch SW1/1 is the Least |
| Significant Bit. The switches have the following |
| decimal values: SW1/6=512, SW1/5=256, SW1/4=128, |
| SW1/3=64, SW1/2=32, SW1/1=16. Turn off the switches |
| and add the values of the switches to obtain the |
| correct memory address. (Off=1, On=0) |
