| CONTROL/STATUS REGISTER ADDRESS SELECTION |
|------------------------------------------------------------|
| A total of 134,217,728 address settings are available. |
| Switches S1 through S7 set the hexadecimal memory address. |
| SW1 is the Most Significant Nibble and switch SW7 is the |
| Least Significant Nibble, though the bottom two bits of |
| SW7 are always 0. The switches have the following decimal |
| weight values: SW1=4,194,304, SW2=2,097,152, |
| SW3=1,048,576, SW4=65,536, SW5=4,096, SW6=256, SW7=16. Set |
| the switches, multiply the number on the switch by its |
| weight value, add the values obtained for each switch, and |
| round down to the nearest multiple of 64 to obtain the |
| correct memory address. |
