CONTROL/STATUS REGISTER ADDRESS SELECTION |
A total of 262,144 address settings are available. Switches S1 through S5 set the hexadecimal memory address. SW1 is the Most Significant Nibble and switch SW5 is the Least Significant Nibble, though the bottom two bits of SW5 are always 0. The switches have the following decimal weight values: SW1=1,048,576, SW2=65,536, SW3=4,096, SW4=256, SW5=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. |
