BASE I/O ADDRESS SELECTION |
A total of 4096 memory address settings are available. The address is selected by setting the hexadecimal numerals on switches SW1-SW3. SW1 is the Most Significant Numeral, and SW3 is the Least Significant Numeral. For example, if SW1 = 2, SW2 = B, and SW3 = 0, the address would be 2B0h. |
