|SW4 sets the I/O addresses for port1, SW 3 sets the I/O |
|addresses for port 2, SW2 sets the I/O addresses for port 3, |
|and SW1 sets the I/O addresses for port 4. A total of 128 base |
|address settings are available. The switches are a binary |
|representation of the decimal memory addresses. SW1-4/1 is the |
|Most Significant Bit and switch SW1-4/7 is the Least |
|Significant Bit. The switches have the following decimal |
|values:SW1-4/1=1024, SW1-4/2=512, SW1-4/3=256, SW1-4/4=128, |
|SW1-4/5=64, SW1-4/6=32, SW1-4/7=16. Turn off the switches and |
|add the values of the switches to obtain the correct memory |
|address. (On=0, Off=1) |

| Note: To share one interrupt on all four ports it is |
| necessary to select the "shared with resistor" setting. |
| |
| For 1-3 ports sharing the same interrupt, select the |
| "shared" setting. |
